2019-01-11Revert "dm: pinctrl: Prevent (re-)configuring pins when already done before ↵Lukasz Majewski
relocation" This reverts commit a7f4b4b344396590845e6552c82829ef68ef9f89. As reported by Alex Kiernan the above optimization introduces a regression in the below use case where: 1. Device has defined 'u-boot,dm-spl' property (@ eMMC DTS node) 2. The device downloads its MLO/SPL via UART (not eMMC - the eMMC pinmux pins are NOT probed/configured in MLO/SPL). 3. The loaded via UART MLO/SPL wants to load Linux from eMMC. In this case the DM core and pinctrl uclass checks 'u-boot,dm-spl' and don't configure pins (as it thinks that those were initialized in MLO/SPL). As we are very close to release - please revert this commit.

2019-01-10dm: usb: udc: Use SEQ_ALIAS to index the USB gadget portsJean-Jacques Hiblot
dfu, fastbot and other usb gadget commands take the USB port index as a parameter. Currently this index is assigned in the order of the driver bindings. Changing this behavior using the SEQ_ALIAS feature. This option assign to the device a SEQ number based on its alias (if it exists) To use it we must set the DM_UC_FLAG_SEQ_ALIAS flag and follow the existing naming convention: use "usb" for the name of the gadget UCLASS_DRIVER (same as for the UCLASS_USB). If no alias is provided, then the index falls back to the order in which the bindings took place.

Commit d0851c893706 ("blk: Call part_init() in the post_probe() method") removed the call to part_init() in mmc.c, as this is done by the DM_MMC framework. However Allwinner is (still) relying on a non-DM MMC driver, so we are now missing the implicit partition init, leading to failing MMC accesses due to the missing partition information.

2019-01-02rockchip: rk3399: Add improved pinctrl driver.Christoph Muellner
The current pinctrl driver for the RK3399 has a range of qulity issues. E.g. it only implements the .set_state_simple() callback, it does not parse the available pinctrl information from the DTS (instead uses hardcoded values), is not flexible enough to cover devices without 'interrupt' field in the DTS (e.g. PWM), is not written generic enough to make code reusable among other rockchip SoCs... This patch addresses these issues by reimplementing the whole driver from scratch using the .set_state() callback. The new implementation covers all featurese of the old code (i.e. it supports pinmuxing and pullup/pulldown configuration). This patch has been tested on a RK3399-Q7 SoM (Puma).

2018-12-29mtd: rawnand: denali: optimize timing parameters for data interfaceMasahiro Yamada
Based on Linux commit 1dfac31a5a63ac04a9b5fbc3f5105a586560f191 This commit improves the ->setup_data_interface() hook. The denali_setup_data_interface() needs the frequency of clk_x and the ratio of clk_x / clk. The latter is currently hardcoded in the driver, like this: #define DENALI_CLK_X_MULT 6 The IP datasheet requires that clk_x / clk be 4, 5, or 6. I just chose 6 because it is the most defensive value, but it is not optimal. By getting the clock rate of both "clk" and "clk_x", the driver can compute the timing values more precisely. To not break the existing platforms, the fallback value, 50 MHz is provided. It is true for all upstreamed platforms. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

For the backward compatibility, the driver still accepts a single clock just as before. The clk_x_rate is taken from the clock driver again if the named clock "clk_x" is available. This will happen only for future DT, hence the existing DT files are not affected. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

commit 4f86a724e82c0 ("power: regulator: denied disable on always-on regulator") throws an error when requested to disable an always-on regulator. It is right that an always-on regulator should not be attempted to be disabled. But at the same time regulator framework should not return an error when such request is received. Instead it should just return success without attempting to disable the specified regulator. This is because the requesting driver will not have the idea if the regulator is always-on or not. The requesting driver will always try to enable/disable regulator as per the required flow. So it is upto regulator framework to not break such scenarios.

This commit prevents from re-configuring pins if those were configured before relocation. Some pins - like UART or DDR must be setup before relocation (as they have 'u-boot,dm-pre-reloc' property set in DTS). Without this change, those pins are re-configured after relocation (pre_reloc_only = 0, so we do not "continue"). Such behavior may be a problem for DDR PAD configuration, as they might be already leveled/tuned with original setup). Signed-off-by: Lukasz Majewski <lukma@denx.de>
