Commit f3729ba6e7b2 ("watchdog: mpc8xx_wdt: Watchdog driver and macros cleanup") switched the watchdog to CONFIG_WATCHDOG. But this is not compatible with the 8xx because it starts the watchdog HW timer at reset and must be serviced from the very beginning including while U-boot is executed in the firmware before relocation in RAM.

2020-02-20mmc: sdhci: fix missing cache invalidation after reading by DMAMasahiro Yamada
This driver currently performs cache operation before the DMA start, but does nothing after the DMA completion. When reading data by DMA, the cache invalidation is needed also after finishing the DMA transfer. Otherwise, the CPU might read data from the cache instead of from the main memory when speculative memory read or memory prefetch occurs. Instead of calling the cache operation directly, this commit adds dma_unmap_single(), which performs cache invalidation internally, but drivers do not need which operation is being run.

2020-02-20mmc: sdhci: use dma_map_single() instead of flush_cache() before DMAMasahiro Yamada
Currently, sdhci_prepare_dma() calls flush_cache() regardless of the DMA direction. Actually, cache invalidation is enough when reading data from the device. This is correctly handled by dma_map_single(), which mimics the DMA-API in Linux kernel. Drivers can be agnostic which cache operation occurs behind the scene. This commit also sanitizes the difference between the virtual address and the dma address. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>

2020-02-19dma-mapping: move dma_map_(un)single() to <linux/dma-mapping.h>Masahiro Yamada
The implementation of dma_map_single() and dma_unmap_single() is exactly the same for all the architectures that support them. Factor them out to <linux/dma-mapping.h>, and make all drivers to include <linux/dma-mapping.h> instead of <asm/dma-mapping.h>. If we need to differentiate them for some architectures, we can move the generic definitions to <asm-generic/dma-mapping.h>. Add some comments to the helpers. The concept is quite similar to the DMA-API of Linux kernel. Drivers are agnostic about what is going on behind the scene. Just call dma_map_single() before the DMA, and dma_unmap_single() after it.

2020-02-19mmc: fsl_esdhc: actually enable cache snooping on mpc830xRasmus Villemoes
The reference manuals for MPC8308 and MPC8309 both say that the esdhcctl aka DMA Control Register "is implemented as SDHCCR" in the System configuration registers. Unfortunately, that doesn't mean that the registers are just mirrors of each other - any write to esdhcctl is simply ignored. So to actually enable cache snooping, we unfortunately have to add a little ifdeffery. There is, naturally, no description of the bit fields of esdhcctl in the MPC8309 manual, but comparing the description of esdhcctl from the LS1021A reference manual to the description of the sdhccr in MPC8309, one also finds that the fields are bit-reversed, so the bit to set is 0x02000000 rather than 0x00000040 - this is also what board_mmc_init() uses in the two gdsys/mpc8308/ boards.

2020-02-17mmc: sdhci-cadence: send tune request twice to work around errataMasahiro Yamada
Cadence sent out an errata report to their customers of this IP. This errata is not so severe, but the tune request should be sent twice to avoid the potential issue. Quote from the report: Problem Summary --------------- The IP6116 SD/eMMC PHY design has a timing issue on receive data path. This issue may lead to an incorrect values of read/write pointers of the synchronization FIFO. Such a situation can happen at the SDR104 and HS200 tuning procedure when the PHY is requested to change a phase of sampling clock when moving to the next tuning iteration. Workarounds ----------- The following are valid workarounds to resolve the issue: 1. In eMMC mode, software sends tune request twice instead of once at each iteration. This means that the clock phase is not changed on the second request so there is no potential for clock instability. 2. In SD mode, software must not use the hardware tuning and instead perform an almost identical procedure to eMMC, using the HRS34 Tune Force register.

2020-02-10regulator: fix: Move code to enable gpio regulator to pre_probe from ↵Lukasz Majewski
ofdata_to_platdata The commit e8e9715df2d4 ("regulator: fixed: Modify enable-active-high behavior") fixed the regulator driver behavior when 'enable-active-high' is defined. Unfortunately, this patch used dm_regulator_platdata()'s "boot_on" member to set GPIOD_IS_OUT_ACTIVE flag and enable the regulator. The issue here is that regulator_common_ofdata_to_platdata() is called _before_ regulator_pre_probe() function in which the 'regulator-boot-on' property is asserted. As a result the GPIOD_IS_OUT_ACTIVE flag is not set and gpio_request_by_name() called in the former function is not enabling the regulator. This is problematic for e.g. i.MX ethernet driver, which then tries to perform initialization without power (and fails). The solution here is to explicitly enable regulator in regulator_pre_probe() callback only when 'regulator-boot-on' property is present in device tree. The GPIOD_IS_OUT_ACTIVE flag is not set at all, but relevant gpio is requested.
