clk/ti/adpll: Make const pointer error a static const array

2021-12-10T01:15:15+00:00

Make const pointer error a static const array, removes a dereference
and shrinks object code a little.

drivers: ti: remove redundant error message in adpll.c

2021-06-28T02:56:45+00:00

There is a error message within devm_ioremap_resource
already, so remove the dev_err call to avoid redundant
error message.

clk: ti: add am33xx/am43xx spread spectrum clock support

2021-06-09T00:49:16+00:00

The patch enables spread spectrum clocking (SSC) for MPU and LCD PLLs.
As reported by the TI spruh73x/spruhl7x RM, SSC is only supported for
the DISP/LCD and MPU PLLs on am33xx/am43xx. SSC is not supported for
DDR, PER, and CORE PLLs.

Calculating the required values and setting the registers accordingly
was taken from the set_mpu_spreadspectrum routine contained in the
arch/arm/mach-omap2/am33xx/clock_am33xx.c file of the u-boot project.

In locked condition, DPLL output clock = CLKINP *[M/N]. In case of
SSC enabled, the reference manual explains that there is a restriction
of range of M values. Since the omap2_dpll_round_rate routine attempts
to select the minimum possible N, the value of M obtained is not
guaranteed to be within the range required. With the new "ti,min-div"
parameter it is possible to increase N and consequently M to satisfy the
constraint imposed by SSC.

clk: ti: omap5: Add missing gpmc and ocmc clkctrl

2021-03-10T11:59:18+00:00

The gpmc clock is needed to update omap5 to boot with genpd with the
related devicetree patches. The ocmc clock is currently not used but
let's add it so we have all the clocks for the l3main2 defined.
