2019-06-21staging: mt7621-pci-phy: remove disable clock from the phy exit functionSergio Paracuellos1-8/+0
The clock which has been used here is not about the phy but the pcie port. It has been properly handled into host pcie driver code. Hence, remove it from here which is the correct thing to do.

2019-04-19staging: mt7621-pci-phy: convert driver to use kernel regmap API'sSergio Paracuellos1-34/+54
Instead of using writel and readl use regmap API which makes the driver maintainability easier. Signed-off-by: Sergio Paracuellos <sergio.paracuellos@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-04-19staging: mt7621-pci-phy: add quirks for 'E2' revision using 'soc_device_attribute'Sergio Paracuellos1-3/+14
Depending on revision of the chip, 'mt7621_bypass_pipe_rst' function must be executed. Add better support for this using 'soc_device_match' in driver probe function. Signed-off-by: Sergio Paracuellos <sergio.paracuellos@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2019-04-19staging: mt7621-pci-phy: remove some unnecessary local variablesSergio Paracuellos1-12/+4
Device tree is not using child nodes anymore so the 'child_np' variable can safely removed. This also simplifies the error path to be able to directly return errors removing also the 'ret' variable.

2019-04-19staging: mt7621-pci-phy: use 'platform_get_resource'Sergio Paracuellos1-6/+5
Driver is using 'of_address_to_resource' to get memory resources. Make use of 'platform_get_resource' instead which is more accurate for a platform driver. This also makes possible to delete a local variable which is not needed anymore.

2019-04-03staging: add missing SPDX lines to Makefile filesGreg Kroah-Hartman1-0/+1

2019-03-29staging: mt7621-pci-phy: change driver to don't use child nodesSergio Paracuellos1-6/+20
Device tree has been simplified to don't use child nodes and use the #phy-cells property instead. Change the driver accordly implementing custom 'xlate' function to return the correct phy for each port.

2019-02-19staging: mt7621-pci-phy: use 'module_init' instead of 'arch_initcall'Sergio Paracuellos1-1/+1
Init driver as 'arch_initcall()' does not work. It causes phy_create() to be called before the phy module is initialized, so 'phy_class' is NULL, the new phy isn't placed in the right class, and it cannot be found. Change to 'module_init()' which works properly in this case.

2019-01-18staging: Mediatek: Use individual config flags in MakefileGeorge Hilliard1-1/+1
These drivers can be useful on other MT76xx SoCs, which have compatible peripherals. The drivers were selectable in Kconfig, but they were quietly excluded from the build because the SOC_MT7621 chip was not selected. So, make the Makefiles use the same flags as Kconfig for these drivers. mt7621-dma and mt7621-dts are left alone because they truly do require that SoC. I have personally confirmed that the mt7621-spi driver works on the MT7688, which was what prompted this change.
