[PATCH v2 5/5] Revert "fdt: translate address if #size-cells = <0>"

This reverts commit d64b9cdcd475eb7f07b49741ded87e24dae4a5fc. As pointed by [1] and [2], the reverted patch made every DT 'reg' property translatable. What the patch was trying to fix was fixed in a different way from previously submitted patches which instead of correcting the generic address

[PATCH v2 4/5] clk: ti: am3-dpll: use custom API for memory access

Using the custom TI functions required not only replacing common memory access functions but also rewriting the routines used to set bypass and lock states. As for readl() and writel(), they also required the address of the register to be accessed, a parameter that is hidden by the TI clk module.

[PATCH v2 1/5] clk: ti: add custom API for memory access

As pointed by [1] and [2], commit d64b9cdcd4 ("fdt: translate address if #size-cells = <0>") is wrong: - It makes every 'reg' DT property translatable. It changes the address translation so that for an I2C 'reg' address you'll get back as reg the I2C controller address + reg value. - The quirk

[PATCH] arm: imx: imx8mm: correct unrecognized fracpll frequency

Frequency requested by ddrphy_init_set_dfi_clk from fracpll uses MHZ() macro, which expands the value provided to the Hz range without taking into account the precise Hz setting. This causes the frequency of 266 MHz not ot be found in the imx8mm_fracpll_tbl, since it is entered there with a

[PATCH v2 0/5] Revert "fdt: translate address if #size-cells = <0>"

As pointed by [1] and [2] the d64b9cdcd4 ("fdt: translate address if #size-cells = <0>") commit was wrong. The series reverts the patch and fixes the issue with platform code, adding custom routines to access the clocks registers. The solution has been inspired by the Linux Kernel code. [1]

[PATCH v2 2/5] clk: ti: change clk_ti_latch() signature

The clock access functions exported by the clk header use the struct clk_ti_reg parameter to get the address of the register. This must also apply to clk_ti_latch(). Changes to TI's clk-mux and clk-divider drivers prevented the patch from generating compile errors. Signed-off-by: Dario Binacchi
