Subject: [PATCH v4 00/11] ARM: davinci: modernize the timer support
Date: Mon, 18 Mar 2019 13:10:49 +0100 [thread overview]
Message-ID: <20190318121100.28132-1-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.
Patch 1 adds a new clocksource driver for davinci.
Patch 2 enables the new driver for device-tree based systems.
Patch 3 adds a WARN_ON() 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 4-5 and 7-10 switch the board files to using the new
clocksource driver while patch 6 moves some necessary defines to
a different place since we'll be removing the file that contains them.
Patch 11 removes legacy timer code.
v1 -> v2:
- changed the license to GPL-only
- dropped regmap usage due to the additional code paths making the
code too slow
- minor code rearrangement
- fixed the da830 timer configuration
- correctly assign the timer halves to clocksource and clockevent
- sqashed the commits adding WARN() when clk_get() fails
- used WARN_ON() and added a return when clk_get() fails to avoid
entering the timer driver without a valid clock
- request the register range before iomapping it
- simplified the configuration structure (dropped the additional
cmp struct)
v2 -> v3:
- use readl/writel_relaxed() instead of __raw variants in the clocksource
driver
- request the memory region before remapping it
- add explanatory comments
- fixed licensing
- used pr_fmt macro
- correctly assign the clocksource name
- use DEFINE_RES_x macros when defining resources to avoid off-by-one
bugs in resource's size
- tweak the commit messages
- don't delete the comments describing the timer usage
- other minor improvements
- rebased on top of Sekhar's soc branch
- dropped patch fixing the clocksource interrupts in device tree (already
upstream)
v3 -> v4:
- fixed formatting of error messages
- fixed comments all around the place
- rebased on top of v5.1-rc1
