Add tps65217 regulator device tree data to AM335x-Bone by adding regulator consumers with tightened constraints and regulator-name. TPS65217 regulator handle can be obtained by using this regulator name. This patch also add I2C node with I2C frequency and tps65217 PMIC I2C slave address. Signed-off-by: AnilKumar Ch <redacted>I tried this and the kernel immediately crashes on my beaglebone. Could you upload the complete git tree and .config you used to test this to somewhere public please?Use this repo to test on beaglebone https://github.com/hvaibhav/am335x-linux/commits/am335x-upstream-staging-pinctrl This wiki talks about how to build and use? https://github.com/hvaibhav/am335x-linux/wiki/How-To-Use-Upstream-Tree Note: Enable tps65217 regulator in kernel config.I used that repo and as a seperate test I rebased that to latest mainline, same thing: as soon as I turn on the TPS in the .config it crashes on boot. Is the pinctrl repo the *exact* repo you used to test the patches on beaglebone?I tested on latest mainline after merging to am335x-upstream-staging-pinctrl (voltage also changing) Can you share your .config and uImage?Config: https://github.com/beagleboard/kernel/blob/beaglebone-3.6/patches/configs/beaglebonequoted
My config details:- (After merge) 1. omap2plus_defconfig 2. Enable tps65217 MFD driver 3. Enable tps65217 regulator driverI rebased onto latest mainline and refreshed the base patches from Vaibhav and I now get: [ 0.246796] tps65217 0-0024: TPS65217 ID 0xf version 1.1 So it boots! I don't know what made it break before, but it's working now :)
*sigh* I'm an idiot: root at beaglebone:~# uname -a Linux beaglebone 3.6.0-rc3-00103-gfd02083 #86 SMP Fri Aug 24 09:45:54 CEST 2012 armv7l GNU/Linux root at beaglebone:~# zcat /proc/config.gz | grep 217 CONFIG_MFD_TPS65217=y # CONFIG_REGULATOR_TPS65217 is not set Will retry with regulator driver actually turned on in a bit.
