2024-02-23phy: constify of_phandle_args in xlateKrzysztof Kozlowski1-1/+1
The xlate callbacks are supposed to translate of_phandle_args to proper provider without modifying the of_phandle_args. Make the argument pointer to const for code safety and readability.

2023-07-24phy: hisilicon: Fix an out of bounds check in hisi_inno_phy_probe()Harshit Mogalapalli1-1/+1
The size of array 'priv->ports[]' is INNO_PHY_PORT_NUM. In the for loop, 'i' is used as the index for array 'priv->ports[]' with a check (i > INNO_PHY_PORT_NUM) which indicates that INNO_PHY_PORT_NUM is allowed value for 'i' in the same loop. This > comparison needs to be changed to >=, otherwise it potentially leads to an out of bounds write on the next iteration through the loop Fixes: ba8b0ee81fbb ("phy: add inno-usb2-phy driver for hi3798cv200 SoC") Reported-by: Dan Carpenter <[email protected]> Signed-off-by: Harshit Mogalapalli <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Vinod Koul <[email protected]>
2023-07-17phy: Explicitly include correct DT includesRob Herring6-2/+8
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2018-03-16phy: add inno-usb2-phy driver for hi3798cv200 SoCPengcheng Li3-0/+208
It adds inno-usb2-phy driver for hi3798cv200 SoC USB 2.0 support. One inno-usb2-phy device can support up to two PHY ports. While there is device level reference clock and power reset to be controlled, each PHY port has its own utmi reset that needs to assert/de-assert as needed. Hi3798cv200 needs to access PHY port0 register via particular peripheral syscon controller register to control PHY, like turning on PHY clock.

2018-02-21phy: add combo phy driver for HiSilicon STB SoCsJianguo Sun3-0/+299
Add combo phy driver for HiSilicon STB SoCs. This phy can be used as pcie-phy, sata-phy or usb-phy. Changes for v5: - Add bindings doc for Hi3798CV200 peripheral controller, and refer to the bindings of this parent node in combphy bindings doc. Changes for v4: - Instead of relying on device id, add a new property hisilicon,fixed-mode for combphy device that doesn't support mode select but a fixed phy mode. - Move combphy mode select register bits definition to device tree, as it may vary from one device to another. Changes for v3: - Make combphy device be child of peripheral controller and use 'reg' property for mapping combphy configuration registers. - Kill "hisilicon,peripheral-syscon" property, since parent node is just the syscon controller now. - Check combphy id to handle the quirk that combphy0 can not configure mode but always works in USB3 mode. - Unify phy .init and .exit hooks for different combphy instances and work modes, as the only quirk we need to handle is that combphy0 can only work in USB3 mode. - Better naming for clock and reset, 'ref' to 'ref_clk', 'por' to 'por_rst'. Changes for v2: - Move DT bindings into a separate patch. - Drop the spurious newline from drivers/phy/Makefile. - Use the phy type defines in dt-bindings/phy/phy.h. - Use PTR_ERR_OR_ZERO() for checking return from devm_of_phy_provider_register(). - Add USB3 phy support.
