2015-11-23ARM: dts: keystone: k2l: fix kernel crash when clk_ignore_unused is not in ↵Murali Karicheri
bootargs Currently kernel crash randomly when K2L EVM is booted without clk_ignore_unused in the bootargs. This workaround is not needed on other K2 devices such as K2HK and K2E and with this fix, we can remove the workaround altogether. netcp driver on K2L uses linked ram on OSR (On chip Static RAM) and requires the clock to this peripheral enabled for proper functioning. This is the reason for the kernel crash. So add the clock node to fix this issue. While at it, remove the workaround documentation as well. With the fix applied, clk_summary dump shows the clock to OSR enabled. cat /sys/kernel/debug/clk/clk_summary ------cut-------------- tcp3d-1 0 0 399360000 0 0 tcp3d-0 0 0 399360000 0 0 osr 1 1 399360000 0 0 fftc-0 0 0 399360000 0 0 -----cut---------------- Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Santosh Shilimkar <ssantosh@kernel.org>
2015-10-13ARM: dts: keystone: enable accumulator channelsMurali Karicheri
Add low priority accumulator channel that can monitor multiple QMSS queues. User for example could use the accumular queue for Netcp Rx completion. While at it, also add an extra line end of each top level node in DTS to make it more readable.

2015-06-10ARM: dts: k2l: fix the netcp range sizeMurali Karicheri
k2l netcp range size is 16M (0x1000000) and not 0xffffff. This patch fixes this. Similarly fix the size of switch module register space to 0x20000. Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: Santosh Shilimkar <ssantosh@kernel.org>
2015-06-10ARM: dts: k2l-evm: Add device bindings for netcp driverMurali Karicheri
This patch enables networking on k2l evm by providing device bindings for netcp, knav, and qmss.
