2014-01-03imx: Easy enabling of SION per-pin using MUX_MODE_SION helper macroOtavio Salvador
The macro allows easy setting in per-pin, as for example: ,---- | imx_iomux_v3_setup_pad(MX6_PAD_NANDF_D1__GPIO_2_1 | MUX_MODE_SION); `---- The IOMUX_CONFIG_SION allows for reading PAD value from PSR register. The following quote from the datasheet: ,---- | ... | 28.4.2.2 GPIO Write Mode | The programming sequence for driving output signals should be as follows: | 1. Configure IOMUX to select GPIO mode (Via IOMUXC), also enable SION if need | to read loopback pad value through PSR | 2. Configure GPIO direction register to output (GPIO_GDIR[GDIR] set to 1b). | 3. Write value to data register (GPIO_DR). | ... `---- This fixes the gpio_get_value to properly work when a GPIO is set for output and has no conflicts. Thanks for Benoît Thébaudeau <benoit.thebaudeau@advansee.com>, Fabio Estevam <fabio.estevam@freescale.com> and Eric Bénard <eric@eukrea.com> for helping to properly trace this down.

2014-01-02mx6: soc: Add the required LDO ramp up delayFabio Estevam
When changing LDO voltages we need to wait for the required amount of time for the voltage to settle. Also, as the timer is still not available when arch_cpu_init() is called, we need to call it later at board_postclk_init() phase. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

2014-01-02mx6: soc: Set the VDDSOC at 1.175 VFabio Estevam
mx6 datasheet specifies that the minimum VDDSOC at 792 MHz is 1.15 V. Add a 25 mV margin and set it to 1.175V. This also matches the VDDSOC voltages for 792MHz operation that the kernel configures: http://git.freescale.com/git/cgit.cgi/imx/linux-2.6-imx.git/tree/arch/arm/mach-mx6/cpu_op-mx6.c?h=imx_3.0.35_4.1.0 Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
2014-01-02mx6: soc: Clear the LDO ramp values up prior to setting the LDO voltagesFabio Estevam
Since ROM may modify the LDO ramp up time according to fuse setting, it is safer to reset the ramp up field to its default value of 00: 00: 64 cycles of 24MHz clock; 01: 128 cycles of 24MHz clock; 02: 256 cycles of 24MHz clock; 03: 512 cycles of 24MHz clock; Signed-off-by: Anson Huang <b20788@freescale.com> Signed-off-by: Jason Liu <r64343@freescale.com> Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>

2013-12-17mx6: clock: Fix the calculation of PLL_ENET frequencyFabio Estevam
According to the mx6 quad reference manual, the DIV_SELECT field of register CCM_ANALOG_PLL_ENETn has the following meaning: "Controls the frequency of the ethernet reference clock. - 00 - 25MHz - 01 - 50MHz - 10 - 100MHz - 11 - 125MHz" Current logic does not handle the 25MHz case correctly, so fix it.

2013-12-17i.MX6 (DQ/DLS): use macros for mux and pad declarationsEric Nelson
This allows the use of either or both declarations from the files mx6q_pins.h and mx6dl_pins.h. All board files should include <asm/arch/mx6-pins.h> with one of the following defined in boards.cfg MX6Q - for boards targeting i.MX6Q or i.MX6D MX6DL - for boards targeting i.MX6DL MX6S - for boards targeting i.MX6S MX6QDL - for boards that support any of the above with run-time detection Pad declarations will be MX6_PAD_x for single-variant boards and MX6Q_PAD_x and MX6DL_PAD_x for boards supporting both processor classes.

2013-11-11arm, am33x: make RTC32K OSC enable configurableHeiko Schocher
As http://www.denx.de/wiki/view/U-Boot/DesignPrinciples#2_Keep_it_Fast states: "Initialize devices only when they are needed within U-Boot" enable the RTC32K OSC only, if CONFIG_SPL_AM33XX_ENABLE_RTC32K_OSC is enabled. Enable this in ti_am335x_common.h, so all boards in mainline should work as before. Signed-off-by: Heiko Schocher <hs@denx.de> Cc: Tom Rini <trini@ti.com>
2013-11-09Merge branch 'iu-boot/master' into 'u-boot-arm/master'Albert ARIBAUD
Conflicts: arch/arm/cpu/arm926ejs/mxs/Makefile board/compulab/cm_t35/Makefile board/corscience/tricorder/Makefile board/ppcag/bg0900/Makefile drivers/bootcount/Makefile include/configs/omap4_common.h include/configs/pdnb3.h Makefile conflicts are due to additions/removals of object files on the ARM branch vs KBuild introduction on the main branch. Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h

2013-11-01ARM: OMAP5: DDR3: Change io settingsSRICHARAN R
The change from 0x64656465 to 0x64646464 is to remove the weak pull enabled on DQS, nDQS lines. This pulls the differential signals in the same direction which is not intended. So disabling the weak pulls improves signal integrity. On the uEVM there are 4 DDR3 devices. The VREF for 2 of the devices is powered by the OMAP's VREF_CA_OUT pins. The VREF on the other 2 devices is powered by the OMAP's VREF_DQ_OUT pins. So the net effect here is that only half of the DDR3 devices were being supplied a VREF! This was clearly a mistake. The second change improves the robustness of the interface and was specifically seen to cure corruption observed at high temperatures on some boards. With the above two changes better memory stability was observed with extended temperature ranges around 100C. Signed-off-by: Sricharan R <r.sricharan@ti.com>
2013-11-01dra7xx_evm: Enabled UART-boot mode and add dra7xx_evm_uart3 buildMinal Shah
UART booting is supported on this SoC, but via UART3 rather than UART1. Because of this we must change the board to use UART3 for all console access (only one UART is exposed on this board and a slight HW mod is required to switch UARTs).
