[RFC,00/12] Device Tree support for SH7751 based board

Message

Yoshinori Sato Aug. 30, 2023, 8:42 a.m. UTC

This is an updated version of something I wrote about 7 years ago.
Minimum support for R2D-plus and LANDISK.
I think R2D-1 will work if you add AX88796 to dts.
And board-specific functions and SCI's SPI functions are not supported.

Yoshinori Sato (12):
  sh: Add OF target boards.
  sh: Update OF handling.
  sh: SH4 OF support.
  clk: SH7750 / 7751 clk driver.
  drivers/irqchip: Add SH7751 and boards specific irqchip.
  drivers/pci: Add SH7751 PCI Host bridge driver.
  clocksource: Update sh_tmu of handling.
  mfd/sm501: Add OF properties.
  of: FDT vaddr support for SH.
  serial/sh-sci: Fix earlyprintk / earlycon.
  sh: target dts.
  sh: OF defconfig.
