Merge tag 'sunxi-drivers-for-4.21' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux into next/drivers

Allwinner drivers changes for 4.21

Those patches are all about our SRAM driver, to enable new SoCs: the
F1c100s, the H5 and the A64 C1 SRAM, that is used by the video decoding
engine.

* tag 'sunxi-drivers-for-4.21' of https://git.kernel.org/pub/scm/linux/kernel/git/sunxi/linux:
  dt-bindings: sram: sunxi: Add compatible for the A64 SRAM C1
  dt-bindings: sram: sunxi: Add bindings for the H5 with SRAM C1
  dt-bindings: sram: Add Allwinner suniv F1C100s
  soc: sunxi: sram: Add support for the H5 SoC system control
  soc: sunxi: sram: Enable EMAC clock access for H3 variant
  soc: sunxi: Change to use DEFINE_SHOW_ATTRIBUTE macro
