From mboxrd@z Thu Jan 1 00:00:00 1970 From: manabian@gmail.com (Joachim Eastwood) Date: Wed, 1 Apr 2015 23:20:37 +0200 Subject: [PATCH 0/6] Add support for NXP LPC18xx family Message-ID: <1427923243-26296-1-git-send-email-manabian@gmail.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org This patch set adds minimal support for the LPC18xx/43xx family of Cortex-M3/4 MCUs from NXP. Patch set is based on Linus master v4.0-rc6. I assume it's too late for 4.1 now, so the target for these patches is 4.2. To keep the amount of dependencies down the PLL1 clock has been hard coded in the lpc18xx.dtsi file. The clock system of LPC18xx is quite advanced for a MCU and requires two clk drivers to work. A patch set with these drivers and update to the dtsi files will be posted separately. Drivers for pinctrl, gpio, ethernet, i2c, rtc and emc (external memories) are also coming for LPC18xx. Right now these can found on: https://github.com/manabian/linux-lpc I don't know the policy on new kernel configs, but if this is a no go the last patch can be dropped. For zImage support: https://patchwork.kernel.org/patch/5505741/ Sucessfuly tested on Embedded Artist LPC4357 Developers Kit.
