2019-02-07soc: amlogic: clk-measure: add axg and g12a supportJerome Brunet1-0/+196
Add support for the axg and g12a SoC family in amlogic clk measure Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Reviewed-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> [khilman: squashed some fixups from Martin] Signed-off-by: Kevin Hilman <khilman@baylibre.com>
2019-02-07soc: amlogic: canvas: Fix meson_canvas_get when probe failedNeil Armstrong1-1/+12
When probe fails, a platforn_device is still associated to the node, but dev_get_drvdata() returns NULL. Handle this case by returning a consistent error.

The call to of_parse_phandle returns a node pointer with refcount incremented thus it must be explicitly decremented here after the last usage.

This patchs adds a missing dependency on REGMAP_MMIO.

2018-11-28soc: amlogic: Add Meson Clock Measure driverNeil Armstrong3-0/+359
The Amlogic Meson SoCs embeds a clock measurer IP to measure the internal clock paths frequencies. The precision is determined by stepping into the duration until the counter overflows. The debugfs slows a pretty summary and each clock can be measured individually aswell.

2018-09-12soc: amlogic: add meson-canvas driverMaxime Jourdan3-0/+193
Amlogic SoCs have a repository of 256 canvas which they use to describe pixel buffers. They contain metadata like width, height, block mode, endianness [..] Many IPs within those SoCs like vdec/vpu rely on those canvas to read/write pixels.

2018-02-12soc: amlogic: meson-gx-pwrc-vpu: fix error on shutdown when domain is powered offHeiner Kallweit1-1/+5
When operating the system headless headless, the domain is never powered on, leaving the clocks disabled. The shutdown function then tries to disable the already disabled clocks, resulting in errors. Therefore call meson_gx_pwrc_vpu_power_off() only if domain is powered on. This patch fixes the described issue on my system (Odorid-C2).

2017-11-30meson-gx-socinfo: Fix package id parsingArnaud Patard1-2/+2
I've noticed the following message while booting a S905X based board: soc soc0: Amlogic Meson GXL (S905D) Revision 21:82 (b:2) Detected The S905D string is obviously wrong. The vendor code does: ... ver = (readl(assist_hw_rev) >> 8) & 0xff; meson_cpu_version[MESON_CPU_VERSION_LVL_MINOR] = ver; ver = (readl(assist_hw_rev) >> 16) & 0xff; meson_cpu_version[MESON_CPU_VERSION_LVL_PACK] = ver; ... while the current code does: ... ... This means that the current mainline code has package id and minor version reversed.

2017-11-09soc: amlogic: meson-gx-pwrc-vpu: fix power-off when powered by bootloaderNeil Armstrong1-10/+19
In the case the VPU power domain has been powered on by the bootloader and no driver are attached to this power domain, the genpd will power it off after a certain amount of time, but the clocks hasn't been enabled by the kernel itself and the power-off will trigger some faults. This patch enable the clocks to have a coherent state for an eventual poweroff and switches to the pm_domain_always_on_gov governor.
