Hi,
some updates for the EZX platform:
[PATCH 1/3] ezx: Add camera support for A780 and A910 EZX phones
[PATCH 2/3] ezx: Add leds-lp3944 support for A910 EZX phone
[PATCH 3/3] ezx: Update ezx_defconfig now that ezx-pcap is in
Are we still in time for 2.6.32?
Ciao ciao,
Antonio

Good that you mentioned this. In fact, I think, that .init should go. So far it is used in pcm990-baseboard.c to initialise pins. You're doing essentially the same - requesting and configuring GPIOs. And it has been agreed, that there is so far no real case, where a static GPIO-configuration wouldn't work. So, I would suggest you remove .init, configure GPIOs statically. And then submit a patch to remove .init completely from struct pxacamera_platform_data. Robert, do you agree?

Good that you mentioned this. In fact, I think, that .init should go. So far it is used in pcm990-baseboard.c to initialise pins. You're doing essentially the same - requesting and configuring GPIOs. And it has been agreed, that there is so far no real case, where a static GPIO-configuration wouldn't work. So, I would suggest you remove .init, configure GPIOs statically. And then submit a patch to remove .init completely from struct pxacamera_platform_data. Robert, do you agree?

The reset happens when bringing the signal from low to high, so holding it high or low it's basically the same here, and given how a780_pxacamera_reset() works I decided to keep it high.

So, what's wrong with that > sequence? it doesn't make sense to reset a powered down device or reset > after init or whatever... > I mean, when probing (or even opening) the device, pxacamera.init() is now called *after* the power ON and reset. If I kept disabled (high) nCAM_EN in init(), as it should've been, this would have overridden the previous power(1) call. Isn't init() in pxacamera platform data meant to initialize the device before it can be powered ON? In fact I am requesting the gpios in a780_pxacamera_init, and if power() or reset() are called before it, then they will be invalid, because the gpios have not been requested yet. Moreover, pxacamera.init() is called in pxa_camera_activate, which is called in pxa_camera_add_device, which in turn is invoked by soc_camera_open() every time. Shouldn't the init() method, where I request gpios, be called only on probe? Let me be more schematic, when probing the camera we have: soc_camera_probe() /* same in soc_camera_open! */ |- icl->power(1) |- icl->reset() |- icd->ops->add() |- pxacamera.init() /* requesting gpios here! */ |- video_dev_create(icd) |- ... Maybe we should have something like: pxacamera.init() /* request gpios only once! on probe. */ soc_camera_probe() /* same in soc_camera_open */ |- icl->power(1) |- icl->reset() |- icd->ops->add() |- video_dev_create(icd) |- ... Or, I'm missing what init() is supposed to do :) Does a patch like this make sense to you? (I've read the other mail about removing .init just before hitting Send, this can be an alternative to removing it, having GPIOs setup in the user driver seems clearer to me.) diff --git a/drivers/media/video/pxa_camera.c b/drivers/media/video/pxa_camera.c index 6952e96..3101bcb 100644 --- a/drivers/media/video/pxa_camera.c +++ b/drivers/media/video/pxa_camera.c @@ -881,18 +882,8 @@ static void recalculate_fifo_timeout(struct pxa_camera_dev *pcdev, static void pxa_camera_activate(struct pxa_camera_dev *pcdev) { - struct pxacamera_platform_data *pdata = pcdev->pdata; - struct device *dev = pcdev->soc_host.v4l2_dev.dev; u32 cicr4 = 0; - dev_dbg(dev, "Registered platform device at %p data %p\n", - pcdev, pdata); - - if (pdata && pdata->init) { - dev_dbg(dev, "%s: Init gpios\n", __func__); - pdata->init(dev); - } - /* disable all interrupts */ __raw_writel(0x3ff, pcdev->base + CICR0); @@ -1651,6 +1644,17 @@ static int __devinit pxa_camera_probe(struct platform_device *pdev) pcdev->res = res; pcdev->pdata = pdev->dev.platform_data; + + dev_dbg(&pdev->dev, "Registered platform device at %p data %p\n", + pcdev, pcdev->pdata); + + if (pcdev->pdata && pcdev->pdata->init) { + dev_dbg(&pdev->dev, "%s: Init gpios\n", __func__); + err = pcdev->pdata->init(&pdev->dev); + if (err) + goto exit_clk; + } + pcdev->platform_flags = pcdev->pdata->flags; if (!(pcdev->platform_flags & (PXA_CAMERA_DATAWIDTH_8 | PXA_CAMERA_DATAWIDTH_9 | PXA_CAMERA_DATAWIDTH_10))) { -- Antonio Ospite http://ao2.it PGP public key ID: 0x4553B001 A: Because it messes up the order in which people normally read text.

If I kept disabled (high) nCAM_EN in init(), as it should've been, this would have overridden the previous power(1) call. Isn't init() in pxacamera platform data meant to initialize the device before it can be powered ON? In fact I am requesting the gpios in a780_pxacamera_init, and if power() or reset() are called before it, then they will be invalid, because the gpios have not been requested yet. Moreover, pxacamera.init() is called in pxa_camera_activate, which is called in pxa_camera_add_device, which in turn is invoked by soc_camera_open() every time. Shouldn't the init() method, where I request gpios, be called only on probe? Let me be more schematic, when probing the camera we have: soc_camera_probe() /* same in soc_camera_open! */ |- icl->power(1) |- icl->reset() |- icd->ops->add() |- pxacamera.init() /* requesting gpios here! */ |- video_dev_create(icd) |- ... Maybe we should have something like: pxacamera.init() /* request gpios only once! on probe. */ soc_camera_probe() /* same in soc_camera_open */ |- icl->power(1) |- icl->reset() |- icd->ops->add() |- video_dev_create(icd) |- ... Or, I'm missing what init() is supposed to do :) Does a patch like this make sense to you? (I've read the other mail about removing .init just before hitting Send, this can be an alternative to removing it, having GPIOs setup in the user driver seems clearer to me.) diff --git a/drivers/media/video/pxa_camera.c b/drivers/media/video/pxa_camera.c index 6952e96..3101bcb 100644 --- a/drivers/media/video/pxa_camera.c +++ b/drivers/media/video/pxa_camera.c @@ -881,18 +882,8 @@ static void recalculate_fifo_timeout(struct pxa_camera_dev *pcdev, static void pxa_camera_activate(struct pxa_camera_dev *pcdev) { - struct pxacamera_platform_data *pdata = pcdev->pdata; - struct device *dev = pcdev->soc_host.v4l2_dev.dev; u32 cicr4 = 0; - dev_dbg(dev, "Registered platform device at %p data %p\n", - pcdev, pdata); - - if (pdata && pdata->init) { - dev_dbg(dev, "%s: Init gpios\n", __func__); - pdata->init(dev); - } - /* disable all interrupts */ __raw_writel(0x3ff, pcdev->base + CICR0); @@ -1651,6 +1644,17 @@ static int __devinit pxa_camera_probe(struct platform_device *pdev) pcdev->res = res; pcdev->pdata = pdev->dev.platform_data; + + dev_dbg(&pdev->dev, "Registered platform device at %p data %p\n", + pcdev, pcdev->pdata); + + if (pcdev->pdata && pcdev->pdata->init) { + dev_dbg(&pdev->dev, "%s: Init gpios\n", __func__); + err = pcdev->pdata->init(&pdev->dev); + if (err) + goto exit_clk; + } + pcdev->platform_flags = pcdev->pdata->flags; if (!(pcdev->platform_flags & (PXA_CAMERA_DATAWIDTH_8 | PXA_CAMERA_DATAWIDTH_9 | PXA_CAMERA_DATAWIDTH_10))) { -- Antonio Ospite http://ao2.it PGP public key ID: 0x4553B001 A: Because it messes up the order in which people normally read text.

* [PATCH 1/3 v3] Add camera support for A780 and A910 EZX phones @ 2009-11-11 11:01 ` Antonio Ospite 0 siblings, 0 replies; 63+ messages in thread From: Antonio Ospite @ 2009-11-11 11:01 UTC (permalink / raw) To: linux-arm-kernel Signed-off-by: Bart Visscher <bartv@thisnet.nl> Signed-off-by: Antonio Ospite <ospite@studenti.unina.it> --- Changes since v2: - Bart's SOB goes first, as he is the original author. - Add MFP_LPM_DRIVE_HIGH to camera gpios, as per Motorola original code. - s/pxacamera/camera/ in function names, as they are not used in pxacamera_platform_data - Adjust comments about CAM_RST which is active on rising edge - Saner default values for nCAM_EN and CAM_RST gpios - Setup gpios statically at board init. Eric, if it is easier for you I can send the three patches together again.
