2015-08-08sunxi: display: Add composite video out supportHans de Goede
Add composite video out support. This only gets enabled on the Mele M3 for now, since that is were it was tested. It will be enabled on more boards after testing. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
2015-08-08sunxi: display: Add support for interlaced modesHans de Goede
Add support for interlaced modes, this is a preparation patch for adding composite out support. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
2015-08-08sunxi: display: Add a few extra register and constant definesHans de Goede
Add a few extra sunxi display registers and constant defines. Also rename some existing defines (e.g. dropping _GCTRL) and make some more generic (e.g. dropping the 2x scaling from SUNXI_LCDC_TCON1_TIMING_V_TOTAL). This is a preparation patch for adding composite video out support. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
2015-08-08sunxi: display: Correct clk_delay calculations for lcd displaysHans de Goede
We should only subtract 2 from the vblank time when using tcon1. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
2015-08-08sunxi: display: Replace #ifdef-ery with helper functionsHans de Goede
All the #ifdef-ery in selecting the default and fallback monitor type is becoming unyielding and makes the code hard to read, replace it with a few helper functions. This will also be useful with the upcoming CHIP board which has display adapter daughterboards which should be runtime detectable.

2015-08-08sunxi: Enable musb in host mode on the Jesurun Q5Hans de Goede
The Jesurun Q5 has the musb hooked up to an usb-a receptacle, enable it in host-only mode. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
2015-08-08sunxi: Do not add a stdout-path alias to dts on boards without a serial portHans de Goede
Do not add a bogus (pointing to a non existing serial port) stdout-path alias to dts on boards without a serial port. Note that we still define CONS_INDEX as this is used by the SPL where we do not use DM_SERIAL and thus CONFIG_REQUIRE_SERIAL_CONSOLE is not honored. We are getting away with this because the sun5i die actually has an uart0, which in the A13 package is not routed to the outside, so we are simply sending SPL bootup messages to the tx pin at the edge of the die, and they go no further from there... And sofar we only have one A13 board which does not have a serial port, all others do have a serial port. This kinda makes sense since the A13 is a much lower pincount package compared to all the other sunxi SoCs.

2015-08-08sunxi: Add CONFIG_USB0_ID_DET setting to 2 more tabletsHans de Goede
Now that we have code to check the id-pin and detect usb-host adapters plugged into the otg port that way, enable it on the tablets which I own. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
2015-08-08sunxi: usb-phy: Never power off the usb portsHans de Goede
USB devices are not really designed to get the power bounced off and on at them. Esp. USB powered harddisks do not like this. Currently we power off the USB ports both on a "usb reset" and when booting the kernel, causing the usb-power to bounce off and then back on again. This patch removes the powering off calls, fixing the undesirable power bouncing. Note this requires some special handling for the OTG port: 1) We must skip the external vbus check if we've already enabled our own vbus to avoid false positives 2) If on an usb reset we no longer detect that the id-pin is grounded, turn off vbus as that means an external vbus may be present now Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

2015-08-08arm: socfpga: misc: Add support for printing FPGA typeDinh Nguyen
Add code which uses the new functions for obtaining FPGA ID from the scan manager. This new code prints the FPGA model attached to the SoCFPGA during boot and sets environment variable "fpgatype", which can be used to determine the FPGA model in U-Boot scripts. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com> Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: scan: Add code to get FPGA IDDinh Nguyen
Add code to get the FPGA type for Altera's SoCFPGA family of FPGA. The code uses the scan manager to send jtag pulses that will return the FPGA ID. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08arm: socfpga: scan: Factor out IO chain programmingMarek Vasut
Factor out the code which sends JTAG instruction followed by data into separate function to tidy the code up a little. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08arm: socfpga: scan: Clean up horrible macrosMarek Vasut
Clean up the horrible macros present in the scan_manager.h . Firstly, the function scan_mgr_io_scan_chain_prg() is static, yet all the macros are used only within it, thus there is no point in having them in the header file. Moreover, the macros are just making the code much less readable, so remove them instead. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08arm: socfpga: scan: Introduce generic JTAG accessorMarek Vasut
Introduce generic function for accessing the JTAG scan chains in the SCC manager. Make use of this function throughout the SCC manager to replace the ad-hoc writes to registers and make the code less cryptic. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08arm: socfpga: scan: Clean up scan_chain_engine_is_idle()Marek Vasut
Rework this function so it's clear that it is only polling for certain bits to be cleared. Add kerneldoc. Fix it's return value to be either 0 on success and -ETIMEDOUT on error and propagate this through the scan manager code.

2015-08-08ddr: altera: sequencer: Clean checkpatch issuesMarek Vasut
Fix most of the dangling checkpatch issues, no functional change. There are still 7 warnings, 1 checks , but those are left in place for the sake of readability of the code. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>

2015-08-08ddr: altera: sequencer: Pluck out misc macros from codeMarek Vasut
Actually convert the sequencer code to use socfpga_sdram_misc_config instead of the various macros. This is just an sed exercise here, no manual coding needed. This patch actually removes the need to include any board-specific files in sequencer.c , so sequencer.c namespace is now no longer poluted by QTS-generated macros. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08ddr: altera: sequencer: Zap SEQ_T(INIT|RESET)_CNTR._VALMarek Vasut
This is another macro used to obfuscate the real code. The T(INIT|RESET)_CNTR._VAL is always defined, so this indirection is unnecessary. Get rid of this. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08ddr: altera: sequencer: Zap VFIFO_SIZEMarek Vasut
Just use READ_VALID_FIFO_SIZE directly, no need for this macro obfuscation. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08ddr: altera: sequencer: Wrap misc remaining macrosMarek Vasut
Introduce structure socfpga_sdram_misc_config to wrap the remaining misc configuration values in board file. Again, introduce a function, socfpga_get_sdram_misc_config(), which returns this the structure. This is almost the final step toward wrapping the nasty QTS generated macros in board files and reducing the pollution of the namespace.

2015-08-08ddr: altera: sequencer: Pluck out IO_* macros from codeMarek Vasut

2015-08-08ddr: altera: sequencer: Wrap IO_* macrosMarek Vasut
Introduce structure socfpga_sdram_io_config to wrap the IO configuration values in board file. Introduce socfpga_get_sdram_io_config() function, which returns this the structure. This is another step toward wrapping the nasty QTS generated macros in board files and reducing the pollution of the namespace.

2015-08-08ddr: altera: sequencer: Wrap RW_MGR_* macrosMarek Vasut
Introduce structure socfpga_sdram_rw_mgr_config to wrap the RW manager configuration values in board file. Introduce a complementary function, socfpga_get_sdram_rwmgr_config(), which returns this the structure. This is another step toward wrapping the nasty QTS generated macros in board files and reducing the pollution of the namespace.

2015-08-08ddr: altera: sequencer: Wrap ac_rom_init and inst_rom_initMarek Vasut
Introduce two wrapper functions, socfpga_get_seq_ac_init() and socfpga_get_seq_inst_init() to avoid direct inclusion of the sequencer_auto_ac_init.h and sequencer_auto_inst_init.h QTS generated files. This reduces namespace pollution again. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08ddr: altera: sequencer: Zap bogus redefinition of RW_MGR_MEM_NUMBER_OF_RANKSMarek Vasut

2015-08-08ddr: altera: sdram: Make sdram_start and sdram_end into u32Marek Vasut
Originally, both sdram_start and sdram_end were 64b values. The sdram_start had no reason for being so, since our address space is only 32b, so switching sdram_start to u32 is simple. The sdram_end is a bit more complex, since it can actually be set to (1 << 32) if someone really wanted to use an SoCFPGA with 4 GiB of DRAM and fixed the code around a little. But, the code handling the protection rules internally decrements the sdram_end variable anyway. Thus, instead of calling the code and passing in the address of the SDRAM end, pass in the address already decremented by one. This lets the sdram_end be 32b as well.

2015-08-08ddr: altera: sdram: Minor cleanup in sdram_get_rule()Marek Vasut

2015-08-08ddr: altera: sdram: Minor cleanup in sdram_set_rule()Marek Vasut
Zap an obscure unneeded cast and clean other minor nits in this function. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08ddr: altera: sdram: Add missing kerneldocMarek Vasut
Add kerneldoc to functions which are missing it, but are already cleaned up. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08ddr: altera: sdram: Clean up sdram_write_verify()Marek Vasut
Clean the function up so that it's obvious what it is doing, fix the formating strings in debug outputs, add kerneldoc. Make the function return proper errno-compliant return values and propagate this change throughout sdram.c Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08ddr: altera: sdram: Clean up sdram_calculate_size() part 2Marek Vasut
Clean up coding style, mostly clean up comments, add kerneldoc. Also, zap assignment of the "cs" variable, which is outright dead code, so just remove it. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08ddr: altera: sdram: Clean up sdram_calculate_size() part 1Marek Vasut
Pluck out all of the CONFIG_HPS_SDR_CTRLCFG_* macros. This change makes sdram.c completely clear of these macros and allows removing of the ugly include of sdram.h . The namespace is now a much nicer place! Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08ddr: altera: sdram: Introduce socfpga_sdram_get_config()Marek Vasut
Introduce socfpga_sdram_get_config() function implement in a board file, which returns the socfpga_sdram_config structure. This is the last step in cleaning up the socfpga_mmr_init_full(), but not the last step which allows removing the inclusion of sdram.h from drivers/ddr/altera/sdram.c thus far. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08ddr: altera: sdram: Clean up sdram_mmr_init_full() part 8Marek Vasut

2015-08-08ddr: altera: sdram: Clean up sdram_mmr_init_full() part 5Marek Vasut
Rework remaining two register setting functions such that they only return the final register value. Move the register setting into the block of register I/O in sdram_mmr_init_full(). Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08ddr: altera: sdram: Clean up sdram_mmr_init_full() part 4Marek Vasut
Merge sdr_set_*() functions which are just setting registers among the sea of register setting in sdram_mmr_init_full(). There is no need to keep them separate this way, there is nothing special about them. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08ddr: altera: sdram: Clean up sdram_mmr_init_full() part 3Marek Vasut
Pluck out the remaining CONFIG_HPS_SDR_CTRLCFG_ and put it into the socfpga_sdram_config structure. Signed-off-by: Marek Vasut <marex@denx.de>
