soc: fsl: qe: fix static checker warning

2021-08-26T12:35:06+00:00

[ Upstream commit c1e64c0aec8cb0499e61af7ea086b59abba97945 ] The patch be7ecbd240b2: "soc: fsl: qe: convert QE interrupt controller to platform_device" from Aug 3, 2021, leads to the following static checker warning: drivers/soc/fsl/qe/qe_ic.c:438 qe_ic_init() warn: unsigned 'qe_ic->virq_low' is never less than zero. In old variant irq_of_parse_and_map() returns zero if failed so unsigned int for virq_high/virq_low was ok. In new variant platform_get_irq() returns negative error codes if failed so we need to use int for virq_high/virq_low. Also simplify high_handler checking and remove the curly braces to make checkpatch happy.

soc: fsl: qe: convert QE interrupt controller to platform_device

2021-08-26T12:35:03+00:00

[ Upstream commit be7ecbd240b2f9ec544d3ce6fccf4cec3cd15dca ] Since 5.13 QE's ucc nodes can't get interrupts from devicetree: ucc@2000 { cell-index = <1>; reg = <0x2000 0x200>; interrupts = <32>; interrupt-parent = <&qeic>; }; Now fw_devlink expects driver to create and probe a struct device for interrupt controller. So lets convert this driver to simple platform_device with probe(). Also use platform_get_ and devm_ family function to get/allocate resources and drop unused .compatible = "qeic".

soc: ixp4xx/qmgr: fix invalid __iomem access

commit a8eee86317f11e97990d755d4615c1c0db203d08 upstream. Sparse reports a compile time warning when dereferencing an __iomem pointer: drivers/soc/ixp4xx/ixp4xx-qmgr.c:149:37: warning: dereference of noderef expression drivers/soc/ixp4xx/ixp4xx-qmgr.c:153:40: warning: dereference of noderef expression drivers/soc/ixp4xx/ixp4xx-qmgr.c:154:40: warning: dereference of noderef expression drivers/soc/ixp4xx/ixp4xx-qmgr.c:174:38: warning: dereference of noderef expression drivers/soc/ixp4xx/ixp4xx-qmgr.c:174:44: warning: dereference of noderef expression Use __raw_readl() here for consistency with the rest of the file. This should really get converted to some proper accessor, as the __raw functions are not meant to be used in drivers, but the driver has used these since the start, so for the moment, let's only fix the warning.

Revert "soc: imx8m: change to use platform driver"

2021-08-12T11:32:03+00:00

[ Upstream commit ac34de14ac30ba4484d68f8845a54b6b6c23db42 ] With the SoC matching changed to a platform driver the match data is available only after other drivers, which may rely on it are already probed. This breaks at least the CAAM driver on i.MX8M. Revert the change until all those drivers have been audited and changed to be able to eal with match data being available later in the boot process.
