Subject: [PULL 21/45] hw/misc: pfsoc: add fabric clocks to ioscb
Date: Mon, 19 Dec 2022 12:16:39 +1000 [thread overview]
Message-ID: <20221219021703.20473-22-alistair.francis@opensource.wdc.com> (raw)
In-Reply-To: <20221219021703.20473-1-alistair.francis@opensource.wdc.com>
From: Conor Dooley <conor.dooley@microchip.com>
On PolarFire SoC, some peripherals (eg the PCI root port) are clocked by
"Clock Conditioning Circuitry" in the FPGA. The specific clock depends
on the FPGA bitstream & can be locked to one particular {D,P}LL - in the
Icicle Kit Reference Design v2022.09 or later this is/will be the case.
Linux v6.1+ will have a driver for this peripheral and devicetrees that
previously relied on "fixed-frequency" clock nodes have been switched
over to clock-controller nodes. The IOSCB region is represented in QEMU,
but the specific region of it that the CCCs occupy has not so v6.1-rcN
kernels fail to boot in QEMU.
Add the regions as unimplemented so that the status-quo in terms of boot
is maintained.
