phy: rockchip-emmc: emmc_phy_init() always return 0

2021-01-13T11:58:24+00:00

rockchip_emmc_phy_init() return variable is not set with the error value
if clk_get() failed. 'emmcclk' is optional, thus use clk_get_optional()
and if the return value != NULL make error processing and set the
return code accordingly.

phy: rockchip-emmc: output tap delay dt property

2020-12-05T08:10:48+00:00

Update the rockchip-emmc phy to set the otapdlysec register with
a dt property. This was mentioned from Brian Norris when he sent
the path to set the default value in the driver.
This patch add a dt property 'output-tapdelay-select' u32 and allow
to set the 0x0-0xf. If not set in dts, the old default 0x4 applies.

Tested with our customized rk3399 to tune the eMMC.

phy: rockchip: set pulldown for strobe line in dts

2020-12-05T08:07:58+00:00

This patch add support to set the internal pulldown via dt property
and allow simplify the board design for the trace from emmc-phy to
the eMMC chipset.
Default to not set the pull-down.

This patch was inspired from the 4.4 tree of the
Rockchip SDK, where it is enabled unconditional.
The patch had been tested with our rk3399 customized board.

phy/rockchip: Make PHY_ROCKCHIP_INNO_HDMI depend on HAS_IOMEM to fix build error

2020-12-02T07:23:46+00:00

devm_ioremap_resource() will be not built in lib/devres.c if
CONFIG_HAS_IOMEM is not set, and then there exists a build
error about undefined reference to "devm_ioremap_resource"
in the file phy-rockchip-inno-hdmi.c under COMPILE_TEST and
CONFIG_PHY_ROCKCHIP_INNO_HDMI, make PHY_ROCKCHIP_INNO_HDMI
depend on HAS_IOMEM to fix it.

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59+00:00

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.
