2022-01-27T07:46:20+00:00

commit 0d375d610fa96524e2ee2b46830a46a7bfa92a9f upstream. This block is used in (at least) T1024 and T1040, including their variants like T1023 etc. Fixes: d55ad2967d89 ("powerpc/mpc85xx: Create dts components for the FSL QorIQ DPAA FMan") Signed-off-by: Tobias Waldekranz Signed-off-by: Jakub Kicinski Signed-off-by: Greg Kroah-Hartman

powerpc/fsl: set fsl,i2c-erratum-a004447 flag for P1010 i2c controllers

2021-06-16T09:34:52+00:00

[ Upstream commit 19ae697a1e4edf1d755b413e3aa38da65e2db23b ] The i2c controllers on the P1010 have an erratum where the documented scheme for i2c bus recovery will not work (A-004447). A different mechanism is needed which is documented in the P1010 Chip Errata Rev L. Signed-off-by: Chris Packham Acked-by: Michael Ellerman Signed-off-by: Wolfram Sang Signed-off-by: Sasha Levin

powerpc/fsl: set fsl,i2c-erratum-a004447 flag for P2041 i2c controllers

[ Upstream commit 7adc7b225cddcfd0f346d10144fd7a3d3d9f9ea7 ] The i2c controllers on the P2040/P2041 have an erratum where the documented scheme for i2c bus recovery will not work (A-004447). A different mechanism is needed which is documented in the P2040 Chip Errata Rev Q (latest available at the time of writing).

powerpc/44x/bamboo: Fix PCI range

2019-12-05T14:26:58+00:00

[ Upstream commit 3cfb9ebe906b51f2942b1e251009bb251efd2ba6 ] The bamboo dts has a bug: it uses a non-naturally aligned range for PCI memory space. This isnt' supported by the code, thus causing PCI to break on this system. This is due to the fact that while the chip memory map has 1G reserved for PCI memory, it's only 512M aligned. The code doesn't know how to split that into 2 different PMMs and fails, so limit the region to 512M. Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Michael Ellerman Signed-off-by: Sasha Levin

powerpc/corenet: explicitly disable the SDHC controller on kmcoge4

2017-11-15T16:13:09+00:00

[ Upstream commit a674c7d470bb47e82f4eb1fa944eadeac2f6bbaf ] It is not implemented on the kmcoge4 hardware and if not disabled it leads to error messages with the corenet32_smp_defconfig.

powerpc/sbc8641: drop bogus PHY IRQ entries from DTS file

2015-12-09T03:00:39+00:00

This file was originally cloned off of the MPC8641D-HPCN reference platform, which actually had a PHY IRQ line connected. However this board does not. The bogus entry was largely inert and went undetected until commit 321beec5047af83db90c88114b7e664b156f49fe ("net: phy: Use interrupts when available in NOLINK state") was added to the tree. With the above commit, the board fails to NFS boot since it sits waiting for a PHY IRQ event that of course never arrives. Removing the bogus entries from the DTS file fixes the issue.
