2022-01-24interconnect: imx: Add imx_icc_get_bw function to set initial avg and peakAbel Vesa1-0/+9
Set the initial avg and peak to 0 in order to avoid setting them to INT_MAX by the interconnect core. Signed-off-by: Abel Vesa <abel.vesa@nxp.com> Link: https://lore.kernel.org/r/20220106170501.3513423-1-abel.vesa@nxp.com Signed-off-by: Georgi Djakov <djakov@kernel.org>
2020-12-28interconnect: imx8mq: Use icc_sync_stateMartin Kepplinger1-0/+2
Add the icc_sync_state callback to notify the framework when consumers are probed and the bandwidth doesn't have to be kept at maximum anymore. Signed-off-by: Martin Kepplinger <martin.kepplinger@puri.sm> Suggested-by: Georgi Djakov <georgi.djakov@linaro.org> Fixes: 7d3b0b0d8184 ("interconnect: qcom: Use icc_sync_state") Link: https://lore.kernel.org/r/20201210100906.18205-6-martin.kepplinger@puri.sm Signed-off-by: Georgi Djakov <georgi.djakov@linaro.org>
2020-12-28interconnect: imx: Remove a useless testChristophe JAILLET1-1/+1
'dn' can't be NULL here, it is tested just the line above. Remove this useless test. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Link: https://lore.kernel.org/r/20201206121322.29434-1-christophe.jaillet@wanadoo.fr Signed-off-by: Georgi Djakov <georgi.djakov@linaro.org>
2020-12-28interconnect: imx: Add a missing of_node_put after of_device_is_availableChristophe JAILLET1-0/+1
Add an 'of_node_put()' call when a tested device node is not available.

Simplify the return expression. Signed-off-by: Liu Shixin <liushixin2@huawei.com> Link: https://lore.kernel.org/r/20200921082437.2591461-1-liushixin2@huawei.com Signed-off-by: Georgi Djakov <georgi.djakov@linaro.org>
2020-09-18interconnect: imx: Simplify with dev_err_probe()Krzysztof Kozlowski1-4/+2
Common pattern of handling deferred probe can be simplified with dev_err_probe(). Less code and the error value gets printed.

2020-05-10interconnect: imx: Fix return value check in imx_icc_node_init_qos()Wei Yongjun1-4/+4
In case of error, the function of_parse_phandle() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.

2020-04-28interconnect: imx: Add platform driver for imx8mmLeonard Crestez3-0/+111
Add a platform driver for the i.MX8MM SoC describing bus topology. Bandwidth adjustments is currently only supported on the DDRC and main NOC. Scaling for the vpu/gpu/display NICs could be added in the future.

2020-04-28interconnect: Add imx core driverLeonard Crestez4-0/+353
This adds support for i.MX SoC family to interconnect framework. Platform drivers can describe the interconnect graph and several adjustment knobs where icc node bandwidth is converted to a DEV_PM_QOS_MIN_FREQUENCY request. The interconnect provider is probed through the main NOC device and other adjustable nodes on the same graph are found from a fsl,scalable-nodes phandle array property.
