* [PATCH v6 1/7] net: phy: broadcom: add bcm54xx_auxctl_read

In-Reply-To: <1478236262-3351-1-git-send-email-jon.mason@broadcom.com>
Add a helper function to read the AUXCTL register for the BCM54xx. This
mirrors the bcm54xx_auxctl_write function already present in the code.

Add the documentation for PHY lane swapping. This is a boolean entry to
notify the phy device drivers that the TX/RX lanes need to be swapped.

* [PATCH v6 3/7] net: phy: broadcom: Add BCM54810 PHY entry
From: Jon Mason @ 2016-11-04 5:10 UTC (permalink / raw)
To: David Miller, Rob Herring, Mark Rutland, Florian Fainelli
Cc: devicetree, netdev, linux-kernel, bcm-kernel-feedback-list, rafal,

In-Reply-To: <1478236262-3351-1-git-send-email-jon.mason@broadcom.com>
The BCM54810 PHY requires some semi-unique configuration, which results
in some additional configuration in addition to the standard config.
Also, some users of the BCM54810 require the PHY lanes to be swapped.
Since there is no way to detect this, add a device tree query to see if
it is applicable.

Add support for the variant of amac hardware present in the Broadcom
Northstar2 based SoCs. Northstar2 requires an additional register to be
configured with the port speed/duplexity (NICPM). This can be added to
the link callback to hide it from the instances that do not use this.
Also, clearing of the pending interrupts on init is required due to
observed issues on some platforms.

We are developing the utils/testcase on OF interface echo system. In one
of the testcase, we want to limit the node and property name length to
32 (max) as per ePAPR specs. This is needed to reuse the DT in multi-OS
environment and so want to maintain ePAPR compliance here.
We are using the above macro for iterating over each node.

I just did few more test using libdrm which had been modified for testing gamma.
And I find you are right. It's my negligence that just tested one case for gamma using all 0xff;

Yes, now gamma correction function behavior weird.
When setting gamma table within crtc enable during initializing, it works correctly. And not right during runtime so far.

* [PATCH v3] clk: mediatek: Allow changing PLL rate when it is off
From: James Liao @ 2016-11-04 6:42 UTC (permalink / raw)

Some modules may need to change its clock rate before turn on it.
So changing PLL's rate when it is off should be allowed.
This patch removes PLL enabled check before set rate, so that
PLLs can set new frequency even if they are off.
On MT8173 for example, ARMPLL's enable bit can be controlled by
other HW. That means ARMPLL may be turned on even if we (CPU / SW)
set ARMPLL's enable bit as 0. In this case, SW may want and can
still change ARMPLL's rate by changing its pcw and postdiv settings.
But without this patch, new pcw setting will not be applied because
its enable bit is 0.

This series is based on v4.9-rc1, add clock and reset controller support
for Mediatek MT2701.
changes since v14:
- Correct commit messages of dts.
- Refine style of init/probe functions.
- Get reg addresses from platform_get_resouce() and devm_ioremap_resource().
- Minor coding style changes.
changes since v13:
- Rebase to v4.9-rc1.
changes since v12:
- Rebase to clk-next.
- Use CLK_OF_DECLARE_DRIVER() instead of CLK_OF_DECLARE().
- Use dev_* and devm_* APIs instead of pr_* and ioremap().
- Refine init functions. Share error messages in common probe().
- Fix null pointer checking for clk_data.
changes since v11:
- Rebase to clk-next.
- Return error code from probe() if clock registration fail.
changes since v10:
- Remove COMMON_CLK dependency from clk/mediatek/Kconfig.
changes since v9:
- Rebase to v4.8-rc1.
- Drop a fix patch of parent clock initial state. It will be replaced by a new
patch from Mike/Stephen.
- Replace clk.h with clk-provider.h.
- Correct register settings of clocks.
changes since v8:
- Rebase to v4.7-rc1.
- Include mt2701-resets.h in mt2701.dtsi.
- Remove an unused property from apmixedsys DT node.
changes since v7:
- Rebase to clk-next.
- Implement subsystem clocks in seperated files.
- Replace critical clock enabling with CLK_IS_CRITICAL flag.
- Reduce most clock registrations in CLK_OF_DECLARE().
- Remove __init and __initconst from most init fucntions and data,
and replace driver registration with platform_driver_register().
- Replace some common function or variable names with unique names.
- Use real clock for UARTs.
changes since v6:
- Rebase to v4.6-rc1.
- Register subsystem clocks in probe() instead of CLK_OF_DECLARE().
- Add clocks that referred by subsystem clocks.
- Fix clk_data size of apmixedsys.
- Add config options for each subsystem clock provider.
changes since v5:
- Rebase to v4.5-rc1 and [1].
- Enable critical clocks for MT2701
- Refine dt-binding documents, add reset controller support for hifsys.
changes since v4:
- Rebase to v4.5-rc1.
- Remove CLK_SET_RATE_PARENT from divider flags.
- Add img_jpgdec_smi clock.
- Move clk/mediatek/Kconfig into menu section in clk/Kconfig.
changes since v3:
- Change the parent of mm_mdp_bls_26m from clk26m to pwm_sel.
changes since v2:
- Fix ethsys definition.
- Replace read-modify-write with regmap_update_bits() in clock operations.
- Move mt2701-resets.h to include/dt-bindings/reset/.
- Add hifsys reset patch from John Crispin.
changes since v1:
- Document MT2701 compatible strings.

In-Reply-To: <1478245388-1412-1-git-send-email-erin.lo@mediatek.com>
From: Shunli Wang <shunli.wang@mediatek.com>
In infrasys and perifsys, there are many reset
control bits for kinds of modules. These bits are
used as actual reset controllers to be registered
into kernel's generic reset controller framework.

From: James Liao <jamesjj.liao@mediatek.com>
Add clock controller nodes for MT2701, include topckgen, infracfg,
pericfg and apmixedsys. This patch also add two oscillators that
provide clocks for MT2701.

We used to use a fixed rate clock for the UARTs. Now that we have clock
support we can associate the correct clocks to the UARTs and drop the
26MHz fixed rate UART clock.

please split this into a separate patch, as code and dts changes need to go
through different branches.
