Add a new address space/memory resource to d_can device tree node. D_CAN RAM initialization is achieved through RAMINIT register which is part of AM33XX control module address space. D_CAN RAM init or de-init should be done by writing instance corresponding value to control module register. Till we have a separate control module driver to write to control module, d_can driver will handle the register writes to control module by itself. So a new address space to represent this control module register is added to d_can driver. Signed-off-by:

Add d_can instances to aliases node to get the D_CAN instance number from the driver. To initialize D_CAN message RAM, corresponding instance number is required. To initialize instance 0 message RAM then 0x1 should be written and for instance 1 message RAM, 0x2 should be written to control module register. With device-tree framework ip instance number is "-1" by default for all instances. To get device id/instance number then modules should be added to DT "aliases" node. of_alias_get_id() gives the device id number based on number of alias nodes present in "aliases node".

omap3_noncore_dpll_set_rate() attempts an enable of bypass clk as well as ref clk for every .set_rate attempt on a noncore DPLL, regardless of whether the .set_rate results in the DPLL being locked or put in bypass. Early at boot, while some of these DPLLs are programmed and locked (using .set_rate for the DPLL), this causes an ordering issue. For instance, on OMAP5, the USB DPLL derives its bypass clk from ABE DPLL. If a .set_rate of USB DPLL which programmes the M,N and locks it is called before the one for ABE, the enable of USB bypass clk (derived from ABE DPLL) then attempts to lock the ABE DPLL and fails as the M,N values for ABE are yet to be programmed. To get rid of this ordering needs, enable bypass clk for a DPLL as part of its .set_rate only when its being put in bypass, and only enable the ref clk when its locked. Reported-by:

WDT1 module can take one of the below clocks as input functional clock - - On-Chip 32K RC Osc [default/reset] - 32K from PRCM The On-Chip 32K RC Osc clock is not an accurate clock-source as per the design/spec, so as a result, for example, timer which supposed to get expired @60Sec, but will expire somewhere ~@40Sec, which is not expected by any use-case. The solution here is to switch the input clock-source to PRCM generated 32K clock-source during boot-time itself. Signed-off-by:
