Subject: [PATCH 00/17] ARM: davinci: modernize the timer support
Date: Fri, 11 Jan 2019 18:21:17 +0100 [thread overview]
Message-ID: <20190111172134.30147-1-brgl@bgdev.pl> (raw)
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
This series removes the legacy timer code from mach-davinci in favor of
a new clocksource driver it introduces.
The first patch fixes a device tree bug that's been around for a while.
Unfortunately any systems shipped with the buggy device will stop booting
once they switch to the new clocksource driver.
Patch 2 adds a new clocksource driver for davinci.
Patch 3 enables the new driver for device-tree based systems.
Patches 4-9 add a WARN() to the machine code of all davinci boards
which is triggered if clk_get() for the timer clock fails. This is needed
as the new driver expects the clock to be functional and doesn't check it.
Patches 10-11 and 13-16 switch the board files to using the new
clocksource driver while patch 12 moves some necessary defines to
a different place since we'll be removing the file that contains them.
Patch 17 removes legacy timer code.
