This patch adds driver for Exynos5422 Dynamic Memory Controller.
The driver provides support for dynamic frequency and voltage scaling
for DMC and DRAM. It supports changing timings of DRAM running with
different frequency. There is also an algorithm to calculate timigns
based on memory description provided in DT.
The patch also contains needed MAINTAINERS file update.

Thanks, applied... or almost. Let's fix it incrementally.

You have two smatch warnings:
  CHECK   ../drivers/memory/samsung/exynos5422-dmc.c
drivers/memory/samsung/exynos5422-dmc.c:272 exynos5_init_freq_table() warn: passing devm_ allocated variable to kfree. 'dmc->opp'
  CHECK   ../drivers/memory/jedec_ddr_data.c
drivers/memory/samsung/exynos5422-dmc.c:565 exynos5_dmc_get_volt_freq() warn: passing zero to 'PTR_ERR'

The second looks like false positive, but first seems to be real.

You have also sparse warning to fix:
../drivers/memory/samsung/exynos5422-dmc.c:736:1: warning: symbol 'exynos5_dmc_align_init_freq' was not declared. Should it be static?

Best regards,
