2018-06-01clk: mvebu: use correct bit for 98DX3236 NANDChris Packham1-1/+1
The correct fieldbit value for the NAND PLL reload trigger is 27. Fixes: commit e120c17a70e5 ("clk: mvebu: support for 98DX3236 SoC") Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2017-01-27clk: mvebu: support for 98DX3236 SoCChris Packham1-0/+23
The 98DX3236, 98DX3336, 98DX4521 and variants have a different TCLK from the Armada XP (200MHz vs 250MHz). The CPU core clock is fixed at 800MHz. The clock gating options are a subset of those on the Armada XP. The core clock divider is different to the Armada XP also.

2014-03-13clk: mvebu: Support Armada 380 SoC on the core divider clockEzequiel Garcia1-0/+23
This commit adds support for the Core Divider clocks of the Armada 380 SoCs. Similarly to Armada 370 and XP, the Core Divider clocks of the 380 have gate capabilities. The only difference is the register layout.

2014-03-13clk: mvebu: Fix ratio register offset on A375 SoCEzequiel Garcia1-1/+1
This commit fixes the ratio register offset which is 0x4, as per the Armada 375 SoC specification.

2014-02-17clk: mvebu: add Armada 375 support to the corediv clock driverThomas Petazzoni1-0/+19
This commit adds support for the Core Divider clocks of the Armada 375. Compared to Armada 370 and XP the Core Divider clocks of the 375 cannot be gated: only their ratio can be changed. This is reflected by the fact that the enable, disable and is_enabled clock operations are not defined, and that the enable_bit_offset field is also undefined.

2014-02-17clk: mvebu: refactor corediv driver to support more SoCThomas Petazzoni1-24/+57
This commit refactors the corediv clock driver so that it is capable of handling various SOCs that have slightly different corediv clock registers and capabilities. It introduces a clk_corediv_soc_desc structure that encapsulates all the SoC specific details.

2013-11-24clk: mvebu: Add Core Divider clockEzequiel Garcia1-0/+223
This commit introduces a new group of clocks present in Armada 370/XP SoCs (called "Core Divider" clocks) and add a provider for them. The only clock supported for now is the NAND clock (ndclk), but the infrastructure to add the rest is already set.
