phy: move from strlcpy with unused retval to strscpy

2022-08-30T07:42:38Z

Follow the advice of the below link and prefer 'strscpy' in this subsystem. Conversion is 1:1 because the return value is not used. Generated by a coccinelle script.

phy: allwinner: phy-sun6i-mipi-dphy: Support D-PHY Rx mode for MIPI CSI-2

2022-04-20T09:10:12Z

The Allwinner A31 D-PHY supports both Rx and Tx modes. While the latter is already supported and used for MIPI DSI this adds support for the former, to be used with MIPI CSI-2. This implementation is inspired by Allwinner's V3s Linux SDK implementation, which was used as a documentation base. It uses the direction dt property to distinguish between tx and rx directions.

phy: sun4i-usb: Add D1 variant

2022-02-25T08:23:21Z

D1 has a register layout like A100 and H616, with the moved SIDDQ bit. Unlike H616 it does not have any dependencies between PHY instances. Signed-off-by: Samuel Holland Link: https://lore.kernel.org/r/20220203013558.11490-4-samuel@sholland.org Signed-off-by: Vinod Koul

phy: sun4i-usb: Rework HCI PHY (aka "pmu_unk1") handling

2022-02-25T08:23:21Z

As Icenowy pointed out, newer manuals (starting with H6) actually document the register block at offset 0x800 as "HCI controller and PHY interface", also describe the bits in our "PMU_UNK1" register. Let's put proper names to those "unknown" variables and symbols. While we are at it, generalise the existing code by allowing a bitmap of bits to clear and set, to cover newer SoCs: The A100 and H616 use a different bit for the SIDDQ control.

phy: sun4i-usb: Remove .disc_thresh where not applicable

2022-02-25T08:23:21Z

.disc_thresh is not used when .type = sun50i_h6_phy, so providing a value for it is misleading. Signed-off-by: Samuel Holland Link: https://lore.kernel.org/r/20220203013558.11490-2-samuel@sholland.org Signed-off-by: Vinod Koul

phy: sun4i-usb: remove enable_pmu_unk1 from sun50i_h6_cfg

2020-11-19T06:19:18Z

For the current code, enable_pmu_unk1 only works in non-a83t and non-h6 types. So let's delete it from the sun50i_h6_cfg. Signed-off-by: Yangtao Li Link: https://lore.kernel.org/r/dc8cbb7b3cd59902a6719f207d18a232903fac8a.1604988979.git.frank@allwinnertech.com Signed-off-by: Vinod Koul

phy: sun4i-usb: explicitly include gpio/consumer.h

phy: allwinner: Make PHY_SUN6I_MIPI_DPHY depend on COMMON_CLK

When CONFIG_ARCH_SUNXI is not set but CONFIG_COMPILE_TEST=y, CONFIG_HAVE_CLK=y, CONFIG_HAVE_LEGACY_CLK=y, there exists the following build errors with CONFIG_PHY_SUN6I_MIPI_DPHY=y: drivers/phy/allwinner/phy-sun6i-mipi-dphy.o: In function `sun6i_dphy_init': phy-sun6i-mipi-dphy.c:(.text+0x320): undefined reference to `clk_set_rate_exclusive' drivers/phy/allwinner/phy-sun6i-mipi-dphy.o: In function `sun6i_dphy_exit': phy-sun6i-mipi-dphy.c:(.text+0x2c8): undefined reference to `clk_rate_exclusive_put' clk_set_rate_exclusive() and clk_rate_exclusive_put() are defined in drivers/clk/clk.c, this file is built under CONFIG_COMMON_CLK, so in order to build drivers/phy/allwinner/phy-sun6i-mipi-dphy.c successful used with various configs, CONFIG_PHY_SUN6I_MIPI_DPHY should depend on CONFIG_COMMON_CLK.
