| * dma-mapping: move dma_map_(un)single() to <linux/dma-mapping.h>Masahiro Yamada2020-02-1912-14/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * mmc: fsl_esdhc: actually enable cache snooping on mpc830xRasmus Villemoes2020-02-191-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * mmc: sdhci-cadence: send tune request twice to work around errataMasahiro Yamada2020-02-171-4/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
