Subject: [U-Boot] [PATCH 0/7] *** Qualcomm Snapdraon serial fixes***
Date: Sat, 12 May 2018 13:15:51 +0300	[thread overview]
Message-ID: <20180512101558.24375-1-ramon.fried@gmail.com> (raw)

In my ongoing effort to get rid of LK (Qualcomm's bootloader) that runs
before U-boot, I found that there were some problems with the uart driver of
Snapdragon.
It appears that the uart only worked because the initialization was previously
done by LK.

While fixing, I also introduced a new pinctrl driver for snapdragon (currently
only enabled for APQ8016).
the pinctrl driver is used for muxing the uart pins and configure the pins IO
properties.

Ramon Fried (7):
  db820c: set clk node to be probed before relocation
  serial: serial_msm: fail probe if settings clocks fails
  serial: serial_msm: initialize uart only before relocation
  mach-snapdragon: Fix UART clock flow
  mach-snapdragon: Introduce pinctrl driver
  db410: added pinctrl node and serial bindings
  serial: serial_msm: added pinmux & config
