[PATCH 0/4] Switch to upstream devicetree for TH1520 platform

[Yao Zi]

This series switches the TH1520 platform along with the only board,
th1520_lpi4a, to use upstream devicetree.

The upstream dt specifies pinctrl configuration for the UART, which is
probed before proper U-Boot relocation. This means we must make
pincontroller, and resource used by the pincontroller available in
relocation. too, so here come PATCH 2 and 3.

Making more drivers bind and probe before relocation raises requirement
of pre-relocation malloc pool, PATCH 1 increases SYS_MALLOC_F_LEN to
0x10000 to fit drivers' usage.

Tested on Lichee Pi 4A 16GiB variant, and it introduces no functionality
regression. Thanks for your time and review.

Yao Zi (4):
  configs: th1520_lpi4a: Enlarge SYS_MALLOC_F_LEN to 0x10000
  clk: thead: th1520-ap: Mark drivers as DM_FLAG_PRE_RELOC
  pinctrl: th1520: Mark driver as DM_FLAG_PRE_RELOC
  dts: th1520: Switch to upstream devicetree
