Date: Fri, 6 Mar 2015 16:12:53 +0100 From: Antoine Tenart <antoine.tenart@...e-electrons.com> To: sebastian.hesselbarth@...il.com, mturquette@...aro.org, sboyd@...eaurora.org Cc: Antoine Tenart <antoine.tenart@...e-electrons.com>, zmxu@...vell.com, jszhang@...vell.com, linux-arm-kernel@...ts.infradead.org, linux-kernel@...r.kernel.org Subject: [PATCH v2 00/11] ARM: berlin: refactor the clock Marvell Berlin SoCs have a chip control register set providing several individual registers dealing with various controllers (pinctrl, reset, clk). This chip controller is described by a single DT node since the individual registers are spread among the chip control register bank. Marvell Berlin also have a system control register set providing several individual registers for pinctrl or adc. A series was sent[1] to correctly handle these two nodes, by using simple-mfd. The series converted the existing pin-controller and reset drivers to take the changes into account. Because the Berlin clock driver was still working with the above modification, Berlin clock reworks were not included into the previous series. Also the clock reworks change some of the clock framework functions, so having a dedicated series helps. This series aims to convert the Berlin clock driver to use the proper way of dealing with the chip and system controller on Berlin SoCs. To do this changes were done in the clk-mux and clk-gate helpers so they can handle regmaps alongside iomem addresses. This series has been tested on the Marvell Berlin BG2Q DMP. This series is based on v4.0-rc1 and [1]. Thanks! Antoine [1] https://lkml.org/lkml/2015/3/6/511 Changes since v1: - Rebased of top of the new version of [1]. - Removed now useless chip and system ctrl compatibles.
