2019-07-31mmc: mv_sdhci: fix uninitialized pointer deref on probeBaruch Siach
Since commit 3d296365e4e8 ("mmc: sdhci: Add support for sdhci-caps-mask") sdhci_setup_cfg() expects a valid sdhci_host mmc field. Move the mmc field initialization before sdhci_setup_cfg() call to avoid crash on mmc pointer dereference.

2019-04-26mmc: mv_sdhci: add driver model supportPierre Bourdon
The new DM implementation currently does not support the Sheeva 88SV331xV5 specific quirk present in the legacy implementation. The legacy code is thus kept for this SoC and others not yet migrated to DM_MMC.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-17mmc: mv_sdhci: zero out sdhci_host structureMatt Pelland
The mv_sdhci driver was not zeroing the sdhci_host structure it allocates causing random access violations in parts of the mmc core where the "ops" member pointers are checked and called if not NULL.

2017-01-23mmc: sdhci: Distinguish between base clock and maximum peripheral frequencyStefan Herbrechtsmeier
The sdhci controller assumes that the base clock frequency is fully supported by the peripheral and doesn't support hardware limitations. The Linux kernel distinguishes between base clock (max_clk) of the host controller and maximum frequency (f_max) of the card interface. Use the same differentiation and allow the platform to constrain the peripheral interface. Signed-off-by: Stefan Herbrechtsmeier <stefan.herbrechtsmeier@weidmueller.com>

This driver did not yet configure the SDHCI MBUS bridge registers. Without this and with CONFIG_MMC_SDMA enabled, mmc hangs at random times. As DMA cannot complete correctly.

2011-11-03mmc: mv_sdhci: fix 8bus width access for 88SV331xV5Lei Wen
Marvell 88SV331xV5 platform's sdhci host control is not very standard with the spec in the 8bit handling. It need to set its private register to switch to the 8bit mode which is not included in the standard sdhci registers. This patch mainly hacks the writeb method, and set its private register if it find the driver is going to switch to the 8bit mode. Signed-off-by: Lei Wen <leiwen@marvell.com>
