2016-07-02pinctrl: uniphier: avoid building unneeded pin-mux tables for SPLMasahiro Yamada
SPL does not use all of the devices, so we can save some memory footprint. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
2016-07-02pinctrl: uniphier: support pin configuration for dedicated pinsMasahiro Yamada
PH1-LD4 and PH1-sLD8 SoCs have pins that support pin configuration (pin biasing, drive strength control), but not pin-muxing. Allow to fill the mux value table with -1 for those pins; pins with mux value -1 will be skipped in the pin-mux set function. The mux value type should be changed from "unsigned" to "int" in order to accommodate -1 as a special case.

2016-07-02pinctrl: uniphier: split pinctrl driver for PH1-LD11 and PH1-LD20Masahiro Yamada
PH1-LD11 and PH1-LD20 have much pin controlling in common, so I added a single driver shared between them in the initial commit. However, the Ethernet pin-mux settings I am going to add are different with each other, and they may diverge more as the progress of development. Split it into two dedicated drivers.

2016-07-02pinctrl: uniphier: allow to have pinctrl node under syscon nodeMasahiro Yamada
Currently, the UniPhier pinctrl driver itself is a syscon, but it turned out much more reasonable to make it a child node of a syscon because our syscon node consists of a bunch of system configuration registers, not only pinctrl, but also phy, and misc registers. It is difficult to split the node. This commit allows to migrate to the new DT structure. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2016-06-28mmc: fsl: introduce wp_enablePeng Fan
Introudce wp_enable. To check WPSPL, wp_enable needs to be set to 1 in board code. Take i.MX6UL for example, for some boards, they do not use WP singal, so they does not configure USDHC1_WP_SELECT_INPUT, and its default value is 0(GPIO1_IO02). However GPIO1_IO02 is muxed for i2c usage and SION bit set. So USDHC controller can always get wp signal and WPSPL shows write protect and blocks driver continuing. This is not what we want to see, so add wp_enable, and if set to 0, just omit the WPSPL checking and this does not effect normal working of usdhc controller. If wp-gpios is provided in dts, wp_enable is set to 1, otherwise 0.

2016-06-28fsl_esdhc: Update clock enable bits for USDHCYe Li
The USDHC moves the 4 clock bits CARD_CLK_SOFT_EN, IPG_PERCLK_SOFT_EN, HCLK_SOFT_EN, and IPG_CLK_SOFT_EN from sysctl register to vendorspec register. The driver uses RSTA to replace the clock gate off operation. But this is not a good solution because: 1. when using RSTA, we should wait this bit to clear by itself. This is not implemeneted in the code. 2. After RSTA is set, it is recommended that the Host Driver reset the external card and reinitialize it. So in this patch, we change to use the vendorspec registers for these bits operation.

2016-06-21net: rtl8169: fix switching between adaptersStephen Warren
The rtl8169 driver uses a global variable to store the register address of the adapter being operated upon. This is updated to point at the correct adapter when sending or receiving a packet, or shutting down the adapter, but not when initializing the adapter. Consequently, switching between different adapters within the same U-Boot runtime does not work correctly since the driver programs the wrong registers during rtl8169_eth_start() -> rtl8169_common_start() -> rtl8169_hw_start(). Note that since rtl8169_eth_stop() does set the global variable, the second consecutive attempt to use the "new" adapter did work even before this patch, because each time network usage is shut down, the network core calls stop, which sets the variable so that the next start does actually initialize the hardware, and the adapter works. Equally, rtl8169_eth_probe() calls rtl_init() which sets the global, so if using only a single device, or if picking the "right" device (based on probe order) when multiple devices are present, ioaddr will already be set correctly from the get-go, so the issue does not occur.

2016-06-19spl: nand: sunxi: add support for NAND config auto-detectionBoris Brezillon
NAND chips are supposed to expose their capabilities through advanced mechanisms like READID, ONFI or JEDEC parameter tables. While those methods are appropriate for the bootloader itself, it's way to complicated and takes too much space to fit in the SPL. Replace those mechanisms by a dumb 'trial and error' mechanism. With this new approach we can get rid of the fixed config list that was used in the sunxi NAND SPL driver.

We also move common setup to a dedicated function (nand_apply_config()) to avoid rewriting the same values in NFC registers each time we read a page. These new functions are passed a pointer to an nfc_config struct to limit the number of parameters.

2016-06-19spl: nand: sunxi: rework status polling loopBoris Brezillon
check_value_xxx() helpers are using a 1ms delay between each test, which can be quite long for some operations (like a page read on an SLC NAND). Since we don't have anything to do but to poll this register, reduce the delay between each test to 1us. While we're at it, rename the max_number_of_retries parameters and the MAX_RETRIES macro into timeout_us and DEFAULT_TIMEOUT_US to reflect that we're actually waiting a given amount of time and not only a number of retries.

2016-06-19spl: nand: sunxi: remove support for so-called 'syndrome' modeBoris Brezillon
The sunxi SPL NAND controller driver supports use 'BootROM'-like configs, that is, configs where the ECC bytes and real data are interleaved in the page instead of putting ECC bytes in the OOB area. Doing that has several drawbacks: - since you're interleaving data and ECC bytes you can't use the whole page otherwise you might override the bad block marker with non-FF bytes. - to solve the bad block marker problem, the ROM code supports partially using the page, but this introduces a huge penalty both in term of read speed and NAND memory usage. While this is fine for rather small binaries(like the SPL one which is at maximum 24KB large), it becomes non-negligible for the bootloader image (several hundred of KB). - auto-detection of the page size is not reliable (this is in my opinion the biggest problem). If you get the page size wrong, you'll end up reading data at a different offset than what was specified by the caller and the reading may succeed (if valid data were written at this address). For all those reasons I think it's wiser to completely remove support for 'syndrome' configs. If we ever need to support it again, then I'd recommend specifying all the config parameters through Kconfig options.

2016-06-19clk: convert API to match reset/mailbox styleStephen Warren
The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).
