It is also in the branch 'am33xx_support_3.5' of > git://git.pwsan.com/linux-2.6. Here is the patch. - Paul From: Vaibhav Hiremath <hvaibhav@xxxxxx> Date: Wed, 18 Apr 2012 15:46:53 -0600 Subject: [PATCH] ARM: OMAP3+: clock33xx: Add AM33XX clock tree data AM33XX clock implementation is different than any existing OMAP family of devices. Although DPLL module is similar to OMAP4 device, but the usage is very much different than OMAP4. AM33XX has different peripheral set and each module gets integrated to the clock framework differently than OMAP family of devices. This patch adds full Clock tree data for AM33XX family of devices and also integrates it into existing OMAP framework.
