Subject: [PATCH 05/48] ARM: pxa: split up mach/hardware.h
Date: Tue, 19 Apr 2022 18:37:27 +0200
Message-Id: <20220419163810.2118169-6-arnd@kernel.org>
X-Mailer: git-send-email 2.29.2
In-Reply-To: <20220419163810.2118169-1-arnd@kernel.org>
References: <20220419163810.2118169-1-arnd@kernel.org>

Precedence: bulk
List-ID: <linux-watchdog.vger.kernel.org>
X-Mailing-List: linux-watchdog@vger.kernel.org

From: Arnd Bergmann <arnd@arndb.de>

The mach/hardware.h is included in lots of places, and it provides
three different things on pxa:

- the cpu_is_pxa* macros
- an indirect inclusion of mach/addr-map.h
- the __REG() and io_pv2() helper macros

Split it up into separate <linux/soc/pxa/cpu.h> and mach/pxa-regs.h
headers, then change all the files that use mach/hardware.h to
include the exact set of those three headers that they actually
need, allowing for further more targeted cleanup.

linux/soc/pxa/cpu.h can remain permanently exported and is now in
a global location along with similar headers. pxa-regs.h and
addr-map.h are only used in a very small number of drivers now
and can be moved to arch/arm/mach-pxa/ directly when those drivers
are to pass the necessary data as resources.

Subject: [PATCH 09/48] watchdog: sa1100: use platform device registration
Date: Tue, 19 Apr 2022 18:37:31 +0200

List-ID: <linux-watchdog.vger.kernel.org>
X-Mailing-List: linux-watchdog@vger.kernel.org

From: Arnd Bergmann <arnd@arndb.de>

Rather than relying on machine specific headers to
pass down the reboot status and the register locations,
use resources and platform_data.

Aside from this, keep the changes to a minimum.
