powerpc: dts: t208x: Disable 10G on MAC1 and MAC2

2022-12-23T01:56:29+00:00

There aren't enough resources to run these ports at 10G speeds. Disable
10G for these ports, reverting to the previous speed.

Merge tag 'powerpc-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

2022-12-19T13:13:33+00:00

Pull powerpc updates from Michael Ellerman:

 - Add powerpc qspinlock implementation optimised for large system
   scalability and paravirt. See the merge message for more details

 - Enable objtool to be built on powerpc to generate mcount locations

 - Use a temporary mm for code patching with the Radix MMU, so the
   writable mapping is restricted to the patching CPU

 - Add an option to build the 64-bit big-endian kernel with the ELFv2
   ABI

 - Sanitise user registers on interrupt entry on 64-bit Book3S

 - Many other small features and fixes

powerpc/dts/fsl: Fix pca954x i2c-mux node names

2022-12-06T12:15:53+00:00

Fix this by renaming pca954x nodes to "i2c-mux", to match the I2C bus
multiplexer/switch DT bindings and the Generic Names Recommendation in
the Devicetree Specification.

powerpc: dts: turris1x.dts: Add channel labels for temperature sensor

2022-11-30T10:46:48+00:00

Channel 0 of SA56004ED chip refers to internal SA56004ED chip sensor (chip
itself is located on the board) and channel 1 of SA56004ED chip refers to
external sensor which is connected to temperature diode of the P2020 CPU.

powerpc/microwatt: Add litesd

This is the register layout of the litesd peripheral for the fusesoc
based Microwatt SoC.

It requires a description of the system clock, which is hardcoded to
100MHz.

powerpc/warp: switch to using gpiod API

2022-11-24T12:31:47+00:00

This switches PIKA Warp away from legacy gpio API and to newer gpiod
API, so that we can eventually deprecate the former.

Because LEDs are normally driven by leds-gpio driver, but the
platform code also wants to access the LEDs during thermal shutdown,
and gpiod API does not allow locating GPIO without requesting it,
the platform code is now responsible for locating GPIOs through device
tree and requesting them. It then constructs platform data for
leds-gpio platform device and registers it. This allows platform
code to retain access to LED GPIO descriptors and use them when needed.

powerpc: dts: qoriq: Add nodes for QSGMII PCSs

2022-10-19T12:25:09+00:00

Now that we actually read registers from QSGMII PCSs, it's important
that we have the correct address (instead of hoping that we're the MAC
with all the QSGMII PCSs on its bus). This adds nodes for the QSGMII
PCSs. They have the same addresses on all SoCs (e.g. if QSGMIIA is
present it's used for MACs 1 through 4).

Since the first QSGMII PCSs share an address with the SGMII and XFI
PCSs, we only add new nodes for PCSs 2-4. This avoids address conflicts
on the bus.

powerpc: Include e500v1_power_isa.dtsi for remaining e500v1 platforms

2022-09-28T09:22:14+00:00

There are still some board device tree files without Power ISA properties
which have Freescale e500v1 cores, namely those which are based on
Freescale mpc8540, mpc8541, mpc8555 and mpc8560 processors.

So include newly introduced e500v1_power_isa.dtsi file in devices tree
files with those processors.

powerpc: Fix SPE Power ISA properties for e500v1 platforms

2022-09-28T09:22:13+00:00

Commit 2eb28006431c ("powerpc/e500v2: Add Power ISA properties to comply
with ePAPR 1.1") introduced new include file e500v2_power_isa.dtsi and
should have used it for all e500v2 platforms. But apparently it was used
also for e500v1 platforms mpc8540, mpc8541, mpc8555 and mpc8560.

e500v1 cores compared to e500v2 do not support double precision floating
point SPE instructions. Hence power-isa-sp.fd should not be set on e500v1
platforms, which is in e500v2_power_isa.dtsi include file.

Fix this issue by introducing a new e500v1_power_isa.dtsi include file and
use it in all e500v1 device tree files.
