mmc: mediatek: Fixed bug where clock frequency could be set wrong

2017-12-20T09:07:23+00:00

[ Upstream commit 40ceda09c8c84694c2ca6b00bcc6dc71e8e62d96 ]

This patch can fix two issues:

Issue 1:
In previous code, div may be overflow when setting clock frequency
as f_min. We can use DIV_ROUND_UP to fix this boundary related
issue.

Issue 2:
In previous code, we can not set the correct clock frequency when
div equals 0xff.

mmc: sdhci-msm: fix issue with power irq

2017-12-09T21:01:48+00:00

[ Upstream commit c7ccee224d2d551f712752c4a16947f6529d6506 ]

SDCC controller reset (SW_RST) during probe may trigger power irq if
previous status of PWRCTL was either BUS_ON or IO_HIGH_V. So before we
enable the power irq interrupt in GIC (by registering the interrupt
handler), we need to ensure that any pending power irq interrupt status
is acknowledged otherwise power irq interrupt handler would be fired
prematurely.

mmc: core: prepend 0x to OCR entry in sysfs

2017-12-05T10:24:33+00:00

commit c892b0d81705c566f575e489efc3c50762db1bde upstream.

The sysfs entry "ocr" was missing the 0x prefix to identify it as hex
formatted.

mmc: s3cmci: include linux/interrupt.h for tasklet_struct

2017-11-08T09:08:33+00:00

[ Upstream commit e1c6ec26b853e9062f0b3daaf695c546d0702953 ]

I got this new build error on today's linux-next

drivers/mmc/host/s3cmci.h:69:24: error: field 'pio_tasklet' has incomplete type
  struct tasklet_struct pio_tasklet;
drivers/mmc/host/s3cmci.c: In function 's3cmci_enable_irq':
drivers/mmc/host/s3cmci.c:390:4: error: implicit declaration of function 'enable_irq';did you mean 'enable_imask'? [-Werror=implicit-function-declaration]

While I haven't found out why this happened now and not earlier, the
solution is obvious, we should include the header that defines
the structure.

mmc: core: add driver strength selection when selecting hs400es

commit fb458864d9a78cc433fec7979acbe4078c82d7a8 upstream.

The driver strength selection is missed and required when selecting
hs400es. So, It is added here.

mmc: sdio: fix alignment issue in struct sdio_func

2017-10-08T08:26:08+00:00

[ Upstream commit 5ef1ecf060f28ecef313b5723f1fd39bf5a35f56 ]

Certain 64-bit systems (e.g. Amlogic Meson GX) require buffers to be
used for DMA to be 8-byte-aligned. struct sdio_func has an embedded
small DMA buffer not meeting this requirement.
When testing switching to descriptor chain mode in meson-gx driver
SDIO is broken therefore. Fix this by allocating the small DMA buffer
separately as kmalloc ensures that the returned memory area is
properly aligned for every basic data type.
