[PATCH 00/22] drm: Convert drivers to drm_simple_encoder_init()
A call to drm_simple_encoder_init() initializes an encoder without further functionality. It only provides the destroy callback to cleanup the encoder's state. Only few drivers implement more sophisticated encoders than that. Most drivers implement such a simple encoder and can use drm_simple_encoder_init() instead. The patchset converts drivers where the encoder's instance is embedded in a larger data structure. The driver releases the memory during cleanup. Each patch replaces drm_encoder_init() with drm_simple_encoder_init() and removes the (now unused) driver's encoder functions. While the patchset is fairly large, the indiviual patches are self- contained and can be merged independently from each other. The simple-encoder functionality is currently in drm-misc-next, where these patches could go as well. Future directions: There's another common case where the driver calls kzalloc() plus drm_encoder_init(). Such drivers are not handled by this patchset. The plan here is to use a simple encoder with either managed memory allocation (once it's merged), or embed the encoder in a larger data structure and drop kzalloc() entirely. The patchset has been compile-tested on x86-64, aarch64 and arm.

[PATCH 06/22] drm/hisilicon/kirin: Use simple encoder
Hi Thomas,
I love your patch! Yet something to improve:

[also build test ERROR on v5.6-rc4]
[cannot apply to rockchip/for-next shawnguo/for-next sunxi/sunxi/for-next

[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to
specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]

But I guess simplifying stuff like you do here will at least give us a nice list of things to look at once we get to the drmm_simple_encoder_init version of all this.

[PATCH 00/22] drm: Convert drivers to drm_simple_encoder_init()

Reviewed-by: Laurent Pinchart <laurent.pinchart at ideasonboard.com> for all the patches. However, I'd like to note that drm_simple_encoder_init() is a bit of a misnommer here. Several of the encoders in those drivers to implement additional functionality. They just expose them through drm_encoder_helper_funcs, not drm_encoder_funcs.> Future directions: There's another common case where the driver > calls kzalloc() plus drm_encoder_init().

It's called 'simple encoder' for the lack of a better name. It's part of the simple KMS helpers, so the name's at least consistent. OTOH I always find drm_simple_display_pipe a bad name. We can still rename the simple-encoder function without much effort. I'm open for suggestions.

Hi Thomas,
I love your patch! Yet something to improve:
[auto build test ERROR on next-20200305]
[also build test ERROR on v5.6-rc4]
[cannot apply to rockchip/for-next shawnguo/for-next sunxi/sunxi/for-next
tegra/for-next linus/master v5.6-rc4 v5.6-rc3 v5.6-rc2]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to
specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
