2023-09-11arm64: dts: renesas: r8a779f0: spider: Enable PCIe Host ch0Yoshihiro Shimoda1-0/+24
Enable PCIe Host controller channel 0 on R-Car S4-8 Spider board. Since this board has an Oculink connector, CLKREQ# pin of PFC for PCIe should not be used. So, using a GPIO is used to output the clock instead. Otherwise the controller cannot detect a PCIe device.

2023-07-27arm64: dts: renesas: spider-cpu: Add GP LEDsGeert Uytterhoeven1-0/+20
Describe the two General Purpose LEDs LED7 and LED8 on the Spider CPU board, so they can be used as indicator LEDs. Note that General Purpose LEDs LED9 to LED11 are not added, as they are connected to GPIO block 4, which can only be accessed from the Control Domain.

2023-01-27arm64: dts: renesas: spider-cpu: Enable UFS deviceYoshihiro Shimoda1-0/+38
Enable UFS device for R-Car S4-8 Spider CPU board. Note that the conditions of RC21012 on the Spider are: - OUT11 (for UFS30_REFCLK_V) is disabled as default. - OUT11 is controlled by GPIO0 pin. - The GPIO0 pin is inverted sense (low active) and pull-up enabled. To output the clock, pin 4 of TCA9554 on the Spider board needs to output low level so that using "gpio-gate-clock" for it.
