2012-07-09crypto: tegra-se: Enable interrupts after clock enableVictor(Weiguo) Pan
Because SE interrupts could be enabled in bootloader, if it's not cleared before jumping into kernel, it continues to assert the interrupt line to interrupt controller. When SE interrupts is enabled in kernel, to access SE registers in IST without clock enabled hung the CPU. To fix this issue, interrupt enabling is moved after clock is enabled. bug 1010334 Change-Id: I1b909efce2c9d92c3112039fc217f7c1360f9bbb Reviewed-on: http://git-master/r/113073 (cherry picked from commit b06e6662f738ad01a3b2b6803db654abaa03385e) Signed-off-by: Victor(Weiguo) Pan <wpan@nvidia.com> Change-Id: Ide4b0295c781e0bba7aa071616e3e6160e44ee76 Reviewed-on: http://git-master/r/114064 Reviewed-by: Automatic_Commit_Validation_User Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>

2011-12-08crypto: tegra-se: fix suspend routine hookupChris Johnson
In platform_pm_suspend, if there's a dev->driver->pm struct, it expects the suspend routine to be filled in there. With a pm struct, it won't use the platform_legacy_suspend path, which is how tegra_se_suspend had been hooked up. This change just moves suspend/resume into the pm ops struct.
